fix: support Windows debug and shared ALSA hosts

[Raphjacksun7]

Purpose

Fix the Windows ARM64 debug-link failure found by a real registry consumer and let Linux applications that already link an older ALSA crate use PocketStation through PipeWire.

Product effect

• Default Windows debug builds link Opus through the current libopus binding.
• native-capture-without-alsa keeps Core Audio, WASAPI, and PipeWire without adding the optional ALSA fallback.
• The normal native-capture feature remains unchanged and still includes ALSA fallback.

Checks

• cargo test --all-features
• cargo test --no-default-features --features native-capture-without-alsa --locked
• strict Clippy and rustfmt
• bash scripts/check_protocol.sh
• Rust API compatibility against 1.1.9
• C ABI and PKSS compatibility

Windows ARM64 debug linking and Linux PipeWire execution are required before merge.

Staff review

1. Purpose and files changed: dependency/linking correction, capture feature selection, CI and public compatibility notes.
2. Product proof enabled: Deepgram and Meetily can consume native capture without unrelated codec or ALSA conflicts.
3. Architecture affected: dependency selection only; Session and capture ownership are unchanged.
4. Evidence: local macOS suites pass; platform jobs and UTM artifacts remain required.
5. Remaining scaffold/mock/loopback: none introduced.
6. Scaffold inventory: n/a.
7. CODE_PROTOCOL: passed locally.
8. Decision: NEEDS MANUAL REVIEW until platform gates pass.
