fix(desktop): restore Soniqo on Sonoma

[ComputelessComputer]

Keep the desktop macOS floor at 14.2, build the Soniqo Swift bridge for macOS 14, and leave macOS 15-only Qwen ASR unavailable.

---

Note

Medium Risk
Build-time manifest patching and split deployment targets (Swift 14 vs MLX 15) affect macOS Apple Silicon builds; Qwen is intentionally removed from the advertised model list.

Overview
Restores Soniqo on macOS 14 (Sonoma) by lowering the Swift bridge to macOS 14.0 while keeping MLX Metal builds on a 15.0 minimum.

The Cargo build now runs swift package resolve, patches the checked-out speech-swift manifest from macOS 15 → 14, and links via SwiftLinker at 14.0. soniqo-swift drops Qwen3ASR; Qwen load paths in the bridge return a clear “requires macOS 15 or newer” error instead of linking MLX Qwen code.

On the Rust side, SoniqoModel::all() lists only Parakeet and Omnilingual (so Qwen no longer appears in the general local-model catalog), while KNOWN still parses Qwen IDs. Platform checks add RequiresMacOs15 and treat Qwen as unavailable on the current platform until macOS 15.

Qwen3 model files can't be deleted after downgrade

Low Severity

delete_model calls ensure_supported_platform, which now rejects Qwen3 models with RequiresMacOs15. Users who previously downloaded Qwen3 model files (up to 1.7 GB) can no longer clean them up through the API — delete_model(Qwen3Small) returns an error instead of removing the cached files. The platform gate makes sense for operations like downloading or transcribing, but blocking deletion of already-cached data leaves orphaned files on disk.
