Rust parity · slice 10/11 — main (never-crash shell)

[ropdias]

Part of #27 · parity v1, slice 10/11 · implemented in #53 (base rust-parity-v1).

Scope

• main.rs + lib.rs: read stdin, take now, resolve the cache dir, render, print. panic::set_hook suppresses backtraces and catch_unwind turns any panic into empty output + exit(0), with panic = "unwind" (never abort).

Bash oracle

The never-crash contract (exit 0 on malformed or empty input).

Done when

• cargo fmt --check, cargo clippy --all-targets -- -D warnings and cargo test are green
• Garbage, empty and partial stdin all exit 0 with no stderr noise
• feat: main — the never-crash imperative shell (parity v1 · slice 10/11) #53 is merged into rust-parity-v1 with a merge commit, not squash or rebase, so the stacked slices above stay valid

#53 targets rust-parity-v1, not the default branch, so closing keywords do not fire. Close this issue by hand when #53 merges, and tick the slice in the #27 checklist.
