CC Uni Gate v0.1.5

Changes

• Keep model discovery cache tied to provider configuration fingerprints so stale provider/model results are pruned after cc-switch changes.
• Automatically refresh missing or stale model discovery cache after reload or cc-switch DB changes.
• Expose the full discovered model list to cc-switch model fetching while keeping actual proxy routing scoped to configured UniGate models.
• Package the macOS zip without AppleDouble resource files to avoid unzip-created files breaking ad-hoc signatures.

Verification

• swift test
• Built and installed the macOS release bundle locally.
• Verified app version 0.1.5 and codesign validation.
• Unzipped the release zip with ordinary unzip, verified codesign, launched the app, and checked /__manager/health.
