Refactor provider metadata lookup so hot paths consult the current process snapshot before falling back to a metadata load.
Centralize provider metadata lookup in the provider runtime and update the focused tests/mocks that exercise embedded-agent and provider loading paths.
Verification:
- node scripts/run-vitest.mjs src/plugins/providers.runtime.consult-current-snapshot.test.ts
- node scripts/run-vitest.mjs src/agents/embedded-agent-runner/run/attempt.cwd-split.test.ts
- node scripts/run-vitest.mjs src/plugins/providers.test.ts
- autoreview --mode branch --base origin/main
- CPU profile loop: current-snapshot resolve 0.459 us/call vs warm direct metadata load 131.493 us/call
- GitHub CI on 728bd53510
