Introduce scap-* crates

[Brendonovich]

Adds a few framework-specific crates for rebuilding Scap on top of:

• scap-screencapturekit for macOS
• scap-direct3d for Windows (D3D11 and probably older versions i need to investigate)
• scap-ffmpeg for maximum efficiency conversions from native buffers to ffmpeg::frame::Video

All these crates focus on providing as much native access as possible with minimal data copying.
Much of the windows code has been adapted from https://github.com/NiiightmareXD/windows-capture

Summary by CodeRabbit

• New Features

  • Introduced cross-platform screen capture: Windows (Direct3D) and macOS (ScreenCaptureKit).
  • Added FFmpeg conversion for captured frames, enabling easy video pipeline integration.
  • Provided configurable capture settings (e.g., FPS, cursor/border visibility) and simple builder-based APIs.
  • Included example CLI tools demonstrating capture and conversion workflows.

• Chores

  • Centralized dependency versions across the workspace (including async and platform libraries).
  • Adjusted CI to make linting non-blocking.

• Documentation

  • Added a README for the macOS capture module.

• Style

  • Minor whitespace cleanup.

Walkthrough

Introduces two new screen capture crates (scap-direct3d for Windows, scap-screencapturekit for macOS) and a cross-platform FFmpeg bridge (scap-ffmpeg) with examples. Centralizes futures via workspace. Adjusts Windows dependencies to workspace/targets. Makes Biome lint non-blocking. Minor manifest tweaks and whitespace edits.

Changes

Cohort / File(s)	Summary
CI workflow .github/workflows/ci.yml	Make Biome lint step non-failing by appending `
Workspace dependency: futures Cargo.toml, apps/desktop/src-tauri/Cargo.toml, crates/editor/Cargo.toml, crates/export/Cargo.toml, crates/media/Cargo.toml, crates/recording/Cargo.toml, crates/rendering/Cargo.toml, crates/rendering-skia/Cargo.toml	Add workspace-level futures = "0.3.31" and switch member crates to futures = { workspace = true }.
Windows deps consolidation crates/camera-directshow/Cargo.toml, crates/camera-mediafoundation/Cargo.toml	Move windows/windows-core to workspace and target-specific blocks; remove non-target global refs.
Camera manifest tweak crates/camera/Cargo.toml	Adjust macOS backend dependency alias entry (name change; path unchanged).
Whitespace crates/camera-directshow/examples/cli.rs	Remove a single blank line; no functional changes.
New crate: scap-direct3d (Windows capture) crates/scap-direct3d/Cargo.toml, crates/scap-direct3d/src/lib.rs, crates/scap-direct3d/examples/cli.rs	Add Windows Graphics Capture/D3D11 capturer API (Display, Settings, Capturer, Frame…), example CLI, and Windows target deps.
New crate: scap-ffmpeg (FFmpeg bridge) crates/scap-ffmpeg/Cargo.toml, crates/scap-ffmpeg/src/lib.rs, crates/scap-ffmpeg/src/direct3d.rs, crates/scap-ffmpeg/src/screencapturekit.rs, crates/scap-ffmpeg/examples/cli.rs	Add AsFFmpeg trait; implement frame conversion for Windows (RGBA) and macOS (NV12/BGRA); provide cross-platform example.
New crate: scap-screencapturekit (macOS capture) crates/scap-screencapturekit/Cargo.toml, crates/scap-screencapturekit/README.md, crates/scap-screencapturekit/src/lib.rs, crates/scap-screencapturekit/src/capture.rs, crates/scap-screencapturekit/src/config.rs, crates/scap-screencapturekit/src/targets.rs, crates/scap-screencapturekit/examples/cli.rs	Add macOS-only capture library: targets (Display/Window), StreamCfgBuilder, Capturer with callbacks, and example CLI.

Poem

In windows of glass and apples that gleam,
I hop through frames like a caffeinated dream.
D3D hums, SCKit sings—what luck!
Futures aligned, our bytes don’t get stuck.
With FFmpeg whiskers, I twitch and I zip—
Capture, convert, and carrot—ship! 🥕🖥️🐇
