STAVAN SHAMUVEL WADEKAR c74cea3d35 feat(mitm): dynamically inject configured models into Antigravity model catalog (#14006)
* feat(mitm): dynamically inject configured models into Antigravity model catalog

- Add /v1internal:fetchAvailableModels to ANTIGRAVITY_TARGET.endpointPatterns in src/mitm/targets/antigravity.ts
- Implement catalog interception and dynamic model merging in AntigravityHandler.intercept() (src/mitm/handlers/antigravity.ts)
- Merge operator's configured combos/models dynamically from the repository into Google Cloud Code's upstream catalog
- Prepend injected models to agentModelSorts recommended group while preserving native models and upstream structure
- Add unit tests covering target endpoint pattern declaration, catalog merging, dynamic combo retrieval, and error propagation in tests/unit/mitm-handler-antigravity.test.ts

Resolves #13959

* test(mitm): isolate DATA_DIR and clean up the combo row in the antigravity catalog test

The DB-backed test ("dynamic catalog pulls configured combos from database
repository") creates a real combo row via src/lib/db/combos.ts, whose module-
level DATA_DIR const resolves once at import time. The PR's own documented
Validation command (`node --import tsx/esm tests/unit/mitm-handler-antigravity.test.ts`)
runs without the `--test` flag, so the existing #10428 eval-probe/test-context
guard in resolveWritableDataDir() never triggers and DATA_DIR falls through to
the real ~/.omniroute home database — writing a permanent test-combo row into
it every run.

Set DATA_DIR to an isolated temp dir at the top of the file (before the
combos.ts import), reset the DB singleton and clean up the temp dir in
test.after(), and wrap the combo creation in try/finally so the created row is
deleted even on assertion failure.

* fix(mitm): prevent model name collision and filter inactive combos in antigravity catalog

* feat(antigravity): integrate native auto groups, fallback to groq, and add bridge proxy

- Inject OmniRoute native auto groups (auto/best-fast, auto/best-coding, auto/best-reasoning, auto/best-free, etc.) into Antigravity IDE & CLI /model selector
- Add bin/antigravity-bridge.mjs with selective proxy routing to isolate native Gemini quota (zero Google token leakage)
- Implement transparent self-healing model remapping to prevent upstream 410 model_shutdown errors on deprecated models
- Update emergencyFallback provider from nvidia to groq/openai/gpt-oss-120b for resilient 0.02s failover

* test(antigravity): add unit test suite for antigravity bridge routing and model self-healing

- Add tests/unit/antigravity-bridge-routing.test.ts covering zero quota leakage for native Gemini models
- Validate OmniRoute auto group routing and display name interception
- Validate retired upstream model self-healing (preventing HTTP 410 crashes)
- Export helper methods from bin/antigravity-bridge.mjs with isMain guard
