fix(worker): schedule experimental GitHub repos

[brendan-kellam]

Summary

• create a recurring repo indexing scheduler when adding a repository through the experimental GitHub endpoint
• retain and rebuild schedulers for connectionless repositories with automatic cleanup disabled
• pass worker settings into the API for the configured reindex interval

Testing

• yarn workspace @sourcebot/backend test --run
• yarn workspace @sourcebot/backend build

Walkthrough

The API now accepts worker settings and schedules recurring repository indexing before triggering an immediate indexing job. Scheduler reconciliation also retains index schedulers for repositories with automatic cleanup disabled.

Changes

Repository indexing lifecycle

Layer / File(s)	Summary
Schedule and trigger repository indexing packages/backend/src/api.ts, packages/backend/src/index.ts	Api receives Settings. Repository indexing upserts a versioned recurring repo-index scheduler and triggers an immediate job with separate priorities. Application wiring passes the settings instance to Api.
Retain schedulers for cleanup-disabled repositories packages/backend/src/reconcileJobSchedulers.ts, packages/backend/src/reconcileJobSchedulers.test.ts	Scheduler reconciliation selects repositories with active connections or disabled automatic cleanup. Tests verify that the corresponding index scheduler remains registered.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟠 High · up to 7a716

The repository-addition endpoint can currently be called without authentication and create persistent indexing schedules, allowing unauthorized users to add repositories and consume worker resources. Merge should be blocked until access control is added.

Incomplete scheduler retention fix

Medium Severity

This change keeps repo-index schedulers for isAutoCleanupDisabled repos during startup reconcile, and the experimental endpoint now creates those schedulers, but connection sync still treats connectionless orphans as removable without checking that flag. After a temporary link/unlink (or connection delete), reconcileRepoIndexWork can drop the scheduler while CLEANUP is skipped, so recurring reindex stops until the next process restart.
