Summary of Changes

This PR addresses several breaking changes and compatibility issues encountered when using @zeklop/opencode-antigravity-auth with OpenCode v2 (e.g. v2.0.12+):

1. Default Export Schema for OpenCode v2 (index.ts):

   • OpenCode v2 requires a default export object containing { id: string, setup: Function }.
   • Added a default export mapping id: "antigravity-auth" and delegating to AntigravityCLIOAuthPlugin.

2. Handle Optional / Undefined directory (src/plugin.ts, src/plugin/config/loader.ts):

   • In OpenCode v2, opencode run --standalone passes directory as undefined when running outside an explicit workspace.
   • getProjectConfigPath previously called join(undefined, ...) which caused TypeError [ERR_INVALID_ARG_TYPE].
   • Now safely falls back to process.cwd() and guards getProjectConfigPath.

3. Guard Interactive CLI Prompts in Non-TTY Environments (src/plugin.ts):

   • OpenCode v2 runs web / server daemon processes where stdin and stdout are not TTYs.
   • Guarded if (inputs) in authorize() with process.stdout?.isTTY && process.stdin?.isTTY to prevent background processes from hanging indefinitely on readline terminal menus.

4. Call .unref() on Background Timers (src/plugin/cache/signature-cache.ts, src/plugin/refresh-queue.ts, src/hooks/auto-update-checker/index.ts):

   • Active setInterval handles kept Node.js event loops alive indefinitely, causing one-shot CLI commands like opencode run "..." to hang after printing the model response.
   • Added .unref() on background intervals and timers so processes exit cleanly when execution finishes.

5. Fix Recursion in Fallback Fetch (src/plugin.ts, src/plugin/request.ts):

   • Guarded isGenerativeLanguageRequest to support string, URL, and Request objects.
   • Delegated non-matching URLs directly to provider?.fetch ?? globalThis.fetch to prevent recursive intercept loops when non-Antigravity requests are made.

Testing

• Ran full test suite (npm test): 41 test files passed, 1029 tests passing.
• Ran npm run build: builds cleanly without errors.
• Verified in OpenCode v2.0.12 CLI and standalone modes.
