What does this PR try to resolve?

The default stance for new "Intentional Artifact" crates is that an RFC is needed, see Crate ownership policy.
However, it gives room for team's to have their charter define the process. As we don't generally need wide input for these decisions, I'm proposing we treat these as "small" changes and only require an FCP.

How should we test and review this PR?

Additional information

That means these will only need an FCP to take ownership, including
updating the charter, rather than an RFC.

Cargo
-----
- [Introduced a new `CARGO_MANIFEST_PATH` environment variable,
  similar to `CARGO_MANIFEST_DIR` but pointing directly to the manifest
  file.]
  (rust-lang/cargo#14404)
- [Added `package.autolib` to the manifest, allowing `[lib]`
  auto-discovery to be disabled.]
  (rust-lang/cargo#14591)
- [Declare support level for each crate in Cargo's Charter / crate docs.]
  (rust-lang/cargo#14600)
- [Declare new Intentional Artifacts as 'small' changes.]
  (rust-lang/cargo#14599)

Rustdoc
-------

- [The sidebar / hamburger menu table of contents now includes the
  `# headers` from the main item's doc comment]
  (rust-lang/rust#120736). This is similar
  to a third-party feature provided by the rustdoc-search-enhancements
  browser extension.

Compatibility Notes
-------------------
- [Warn against function pointers using unsupported ABI strings.]
  (rust-lang/rust#128784)
- [Check well-formedness of the source type's signature in fn
  pointer casts.]
  (rust-lang/rust#129021) This partly closes
  a soundness hole that comes when casting a function item to
  function pointer
- [Use equality instead of subtyping when resolving type dependent paths.]
  (rust-lang/rust#129073)
- Linking on macOS now correctly includes Rust's default deployment
  target. Due to a linker bug, you might have to pass
  `MACOSX_DEPLOYMENT_TARGET` or fix your `#[link]` attributes to
  point to the correct frameworks. See
  <rust-lang/rust#129369>.
- [Rust will now correctly raise an error for `repr(Rust)` written
  on non-`struct`/`enum`/`union` items, since it previous did not
  have any effect.]
  (rust-lang/rust#129422)
- The future incompatibility lint `deprecated_cfg_attr_crate_type_name`
  [has been made into a hard error]
  (rust-lang/rust#129670). It was used to
  deny usage of `#![crate_type]` and `#![crate_name]` attributes in
  `#![cfg_attr]`, which required a hack in the compiler to be able
  to change the used crate type and crate name after cfg expansion.
  Users can use `--crate-type` instead of `#![cfg_attr(..., crate_type
  = "...")]` and `--crate-name` instead of `#![cfg_attr(...,
  crate_name = "...")]` when running `rustc`/`cargo rustc` on the
  command line.  Use of those two attributes outside of `#![cfg_attr]`
  continue to be fully supported.

- Until now, paths into the sysroot were always prefixed with
  `/rustc/$hash` in diagnostics, codegen, backtrace, e.g.
    ```
    thread 'main' panicked at 'hello world', map-panic.rs:2:50
    stack backtrace:
       0: std::panicking::begin_panic
                 at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/std/src/panicking.rs:616:12
       1: map_panic::main::{{closure}}
                 at ./map-panic.rs:2:50
       2: core::option::Option<T>::map
                 at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/core/src/option.rs:929:29
       3: map_panic::main
                 at ./map-panic.rs:2:30
       4: core::ops::function::FnOnce::call_once
                 at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/core/src/ops/function.rs:248:5
    note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.
    ```
  [RFC 3127 said]
  (https://rust-lang.github.io/rfcs/3127-trim-paths.html#changing-handling-of-sysroot-path-in-rustc)
  > We want to change this behaviour such that, when `rust-src`
    source files can be discovered, the virtual path is discarded
    and therefore the local path will be embedded, unless there is
    a `--remap-path-prefix` that causes this local path to be remapped
    in the usual way.

    [#129687](rust-lang/rust#129687)
    implements this behaviour, when `rust-src` is present at compile
    time, `rustc` replaces `/rustc/$hash` with a real path into
    the local `rust-src` component with best effort.  To sanitize
    this, users must explicitly supply `--remap-path-prefix=<path
    to rust-src>=foo` or not have the `rust-src` component installed.
- The allow-by-default `missing_docs` lint used to disable itself
  when invoked through `rustc --test`/`cargo test`, resulting in
  `#[expect(missing_docs)]` emitting false positives due to the
  expectation being wrongly unfulfilled. This behavior [has now been
  removed]
  (rust-lang/rust#130025), which allows
  `#[expect(missing_docs)]` to be fulfilled in all scenarios, but
  will also report new `missing_docs` diagnostics for publicly
  reachable `#[cfg(test)]` items, [integration test]
  (https://doc.rust-lang.org/cargo/reference/cargo-targets.html#integration-tests)
  crate-level documentation, and publicly reachable items in
  integration tests.
- [The `armv8r-none-eabihf` target now uses the Armv8-R required
  set of floating-point features.]
  (rust-lang/rust#130295)
- [Fix a soundness bug where rustc wouldn't detect unconstrained
  higher-ranked lifetimes in a `dyn Trait`'s associated types that
  occur due to supertraits.]
  (rust-lang/rust#130367)
- [Update the minimum external LLVM version to 18.]
  (rust-lang/rust#130487)
- [Remove `aarch64-fuchsia` and `x86_64-fuchsia` target aliases in
  favor of `aarch64-unknown-fuchsia` and `x86_64-unknown-fuchsia`
  respectively.]
  (rust-lang/rust#130657)
- [The ABI-level exception class of a Rust panic is now encoded
  with native-endian bytes, so it is legible in hex dumps.]
  (rust-lang/rust#130897)
- [Visual Studio 2013 is no longer supported for MSVC targets.]
  (rust-lang/rust#131070)
- [The sysroot no longer contains the `std` dynamic library in its
  top-level `lib/` dir.]
  (rust-lang/rust#131188)

<a id="1.83.0-Cargo"></a>

## Cargo

-   [Introduced a new `CARGO_MANIFEST_PATH` environment variable, similar to `CARGO_MANIFEST_DIR` but pointing directly to the manifest file.](rust-lang/cargo#14404)
-   [Added `package.autolib` to the manifest, allowing `[lib]` auto-discovery to be disabled.](rust-lang/cargo#14591)
-   [Declare support level for each crate in Cargo's Charter / crate docs.](rust-lang/cargo#14600)
-   [Declare new Intentional Artifacts as 'small' changes.](rust-lang/cargo#14599)

<a id="1.83-Rustdoc"></a>

## Rustdoc

-   [The sidebar / hamburger menu table of contents now includes the `# headers` from the main item's doc comment](rust-lang/rust#120736). This is similar to a third-party feature provided by the rustdoc-search-enhancements browser extension.

<a id="1.83.0-Compatibility-Notes"></a>

## Compatibility Notes

-   [Warn against function pointers using unsupported ABI strings.](rust-lang/rust#128784)
-   [Check well-formedness of the source type's signature in fn pointer casts.](rust-lang/rust#129021) This partly closes a soundness hole that comes when casting a function item to function pointer
-   [Use equality instead of subtyping when resolving type dependent paths.](rust-lang/rust#129073)
-   Linking on macOS now correctly includes Rust's default deployment target. Due to a linker bug, you might have to pass `MACOSX_DEPLOYMENT_TARGET` or fix your `#[link]` attributes to point to the correct frameworks. See [#&#8203;129369](rust-lang/rust#129369).
-   [Rust will now correctly raise an error for `repr(Rust)` written on non-`struct`/`enum`/`union` items, since it previous did not have any effect.](rust-lang/rust#129422)
-   The future incompatibility lint `deprecated_cfg_attr_crate_type_name` [has been made into a hard error](rust-lang/rust#129670). It was used to deny usage of `#![crate_type]` and `#![crate_name]` attributes in `#![cfg_attr]`, which required a hack in the compiler to be able to change the used crate type and crate name after cfg expansion.
    Users can use `--crate-type` instead of `#![cfg_attr(..., crate_type = "...")]` and `--crate-name` instead of `#![cfg_attr(..., crate_name = "...")]` when running `rustc`/`cargo rustc` on the command line.
    Use of those two attributes outside of `#![cfg_attr]` continue to be fully supported.
-   Until now, paths into the sysroot were always prefixed with `/rustc/$hash` in diagnostics, codegen, backtrace, e.g.

        thread 'main' panicked at 'hello world', map-panic.rs:2:50
        stack backtrace:
           0: std::panicking::begin_panic
                     at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/std/src/panicking.rs:616:12
           1: map_panic::main::{{closure}}
                     at ./map-panic.rs:2:50
           2: core::option::Option<T>::map
                     at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/core/src/option.rs:929:29
           3: map_panic::main
                     at ./map-panic.rs:2:30
           4: core::ops::function::FnOnce::call_once
                     at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/core/src/ops/function.rs:248:5
        note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.

    [RFC 3127 said](https://rust-lang.github.io/rfcs/3127-trim-paths.html#changing-handling-of-sysroot-path-in-rustc)

    > We want to change this behaviour such that, when `rust-src` source files can be discovered, the virtual path is discarded and therefore the local path will be embedded, unless there is a `--remap-path-prefix` that causes this local path to be remapped in the usual way.

    [#&#8203;129687](rust-lang/rust#129687) implements this behaviour, when `rust-src` is present at compile time, `rustc` replaces `/rustc/$hash` with a real path into the local `rust-src` component with best effort.
    To sanitize this, users must explicitly supply `--remap-path-prefix=<path to rust-src>=foo` or not have the `rust-src` component installed.
-   The allow-by-default `missing_docs` lint used to disable itself when invoked through `rustc --test`/`cargo test`, resulting in `#[expect(missing_docs)]` emitting false positives due to the expectation being wrongly unfulfilled. This behavior [has now been removed](rust-lang/rust#130025), which allows `#[expect(missing_docs)]` to be fulfilled in all scenarios, but will also report new `missing_docs` diagnostics for publicly reachable `#[cfg(test)]` items, [integration test](https://doc.rust-lang.org/cargo/reference/cargo-targets.html#integration-tests) crate-level documentation, and publicly reachable items in integration tests.
-   [The `armv8r-none-eabihf` target now uses the Armv8-R required set of floating-point features.](rust-lang/rust#130295)
-   [Fix a soundness bug where rustc wouldn't detect unconstrained higher-ranked lifetimes in a `dyn Trait`'s associated types that occur due to supertraits.](rust-lang/rust#130367)
-   [Update the minimum external LLVM version to 18.](rust-lang/rust#130487)
-   [Remove `aarch64-fuchsia` and `x86_64-fuchsia` target aliases in favor of `aarch64-unknown-fuchsia` and `x86_64-unknown-fuchsia` respectively.](rust-lang/rust#130657)
-   [The ABI-level exception class of a Rust panic is now encoded with native-endian bytes, so it is legible in hex dumps.](rust-lang/rust#130897)
-   [Visual Studio 2013 is no longer supported for MSVC targets.](rust-lang/rust#131070)
-   [The sysroot no longer contains the `std` dynamic library in its top-level `lib/` dir.](rust-lang/rust#131188)
