Benjamin Carlsson da20788df9 Bundle Linux voice runtimes and improve audio reliability (#44714)
## Why

Linux voice needs system ALSA plugins and enough buffering to accommodate PipeWire graph cycles without losing capture samples. Voice startup failures also need actionable diagnostics without exposing native error details.

## What changed

- Build and bundle GNU voice helpers and runtimes with primary Linux musl release archives, and sign the archives. Keep Python wheels free of these libraries to preserve `manylinux_2_17` compatibility.
- Discover ALSA plugins in fixed system directories and increase Linux capture and playback buffering to support larger PipeWire graph cycles.
- Report voice failures by stage, preserve negotiation timeout classification, and discard native error sources. Suppress the misleading `requested` closure message after failure cleanup.
- Add explicit Windows MSVC, pkgconf, and CMake toolchain configuration and preserve host architecture in native build environments.

## Testing

Add coverage for Linux release assembly, ALSA plugin discovery, PipeWire capture and playback, classified startup failures, failure cleanup rendering, and Windows build environment handling.

Workflow Strategy

The workflows in this directory are split so that pull requests get fast, review-friendly signal while main still gets the full cross-platform verification pass.

Pull Requests

  • Required checks run against GitHub's synthetic merge commit, not the pull request head alone. This includes changes already on main and catches conflicts before they reach the branch.
  • bazel.yml is the main pre-merge verification path for Rust code. It runs Bazel test and Bazel clippy on the supported Bazel targets, including the generated Rust test binaries needed to lint inline #[cfg(test)] code.
  • rust-ci.yml keeps the Cargo-native PR checks intentionally small:
    • cargo fmt --check
    • cargo shear
    • argument-comment-lint on Linux, macOS, and Windows
    • tools/argument-comment-lint package tests when the lint or its workflow wiring changes

Post-Merge On main

  • bazel.yml also runs on pushes to main. This re-verifies the merged Bazel path and helps keep the BuildBuddy caches warm.
  • rust-ci-full.yml is the full Cargo-native verification workflow. It keeps the heavier checks off the PR path while still validating them after merge:
    • the full Cargo clippy matrix
    • the full Cargo nextest matrix via per-platform archive-backed shards
    • Windows ARM64 nextest archives cross-compiled on Windows x64, then replayed on native Windows ARM64 shards
    • release-profile Cargo builds
    • cross-platform argument-comment-lint
    • Linux remote-env tests

Rule Of Thumb

  • If a build/test/clippy check can be expressed in Bazel, prefer putting the PR-time version in bazel.yml.
  • Keep rust-ci.yml fast enough that it usually does not dominate PR latency.
  • Reserve rust-ci-full.yml for heavyweight Cargo-native coverage that Bazel does not replace yet.
