Add support for importing and reusing the Antigravity CLI (agy) OAuth token, so the proxy can authenticate without a separate browser OAuth flow or a full Antigravity IDE installation. Key changes: - New 'agy' account source: reads ~/.gemini/antigravity-cli/antigravity-oauth-token and refreshes the token using the same OAuth client_id/secret the proxy already hardcodes (agy uses the same Google OAuth client). Optional write-back of refreshed access tokens via AGY_TOKEN_WRITEBACK=1. - CLI command 'import-agy' (npm run accounts:import-agy) to import the agy token, resolve the account email, and save it as source='agy'. - --no-webui flag (or DISABLE_WEBUI/NO_WEBUI env vars) to disable the WebUI for headless/API-only deployments, saving ~30-50MB RAM. - /anthropic prefix alias: rewrites /anthropic/v1/* → /v1/* so third-party tools (e.g. Hermes Agent) that auto-detect Anthropic-compatible endpoints via URL suffix heuristic work out of the box. - Schema sanitizer fix: convert non-string enum/const values to strings (Google Cloud Code API rejects boolean/number enum values with TYPE_STRING errors).

Summary
This PR adds three features that make the proxy work headlessly alongside the Antigravity CLI (agy) and third-party tools like Hermes Agent:
1. Reuse agy CLI OAuth Token (source: 'agy')
The standalone Antigravity CLI (agy) stores its Google OAuth token at ~/.gemini/antigravity-cli/antigravity-oauth-token. Crucially, agy uses the same Google OAuth client_id + client_secret that this proxy already hardcodes in OAUTH_CONFIG. This means the proxy can refresh agy's refresh_token directly — no separate browser OAuth flow and no full Antigravity IDE installation required.
This is the same pattern used by hermes-claude-auth (reusing ~/.claude/.credentials.json) and opencode-antigravity-auth.
New CLI command:
```bash
npm run accounts:import-agy
AGY_TOKEN_PATH=/custom/path npm run accounts:import-agy
```
New env vars:
2. --no-webui Flag
Disables the WebUI for headless servers. Saves ~30-50MB RAM.
```bash
npm start -- --no-webui
DISABLE_WEBUI=1 npm start
```
3. /anthropic Prefix Alias
Third-party tools (e.g. Hermes Agent) auto-detect Anthropic-compatible endpoints via URL suffix heuristic (/anthropic). This PR adds middleware that rewrites /anthropic/v1/* → /v1/*.
4. Schema Sanitizer Fix
Google's Cloud Code API rejects non-string enum values. The schema sanitizer was converting const: true (boolean) to enum: [true] (boolean array), which Google rejected. This PR converts all enum/const values to strings.
