Subject: [PATCH] fix(github): fix several bugs in github action index.ts

- Add missing `isScheduleEvent()` function that was called but never
  defined, causing a ReferenceError at runtime
- Use `MENTIONS` env var in `assertPayloadKeyword()` and `getUserPrompt()`
  instead of hardcoded `/opencode` and `/oc` trigger phrases
- Fix `useEnvGithubToken()` to check `USE_GITHUB_TOKEN` flag and read
  `GITHUB_TOKEN` env var, matching the action.yml configuration
- Add `useEnvOidcBaseUrl()` to support configurable `OIDC_BASE_URL` env
  var instead of hardcoded `https://api.opencode.ai`
