Summary:
- Strip the redundant `google/` provider prefix before embedding Google Vertex model ids under `/publishers/google/models/`.
- Keep bare Vertex model ids unchanged.
- Add regression coverage for the provider-qualified Vertex path.
Verification:
- `node_modules/.bin/oxfmt --check --threads=1 extensions/google/transport-stream.ts extensions/google/transport-stream.test.ts`
- `node scripts/run-oxlint.mjs extensions/google/transport-stream.ts extensions/google/transport-stream.test.ts`
- `node scripts/run-vitest.mjs extensions/google/transport-stream.test.ts --maxWorkers=1 -t 'strips redundant google provider prefixes from Google Vertex model paths'`
