Task 01: Backend Issue-Link Reverse Lookup

Acceptance

• A workspace-scoped endpoint returns valid metadata-backed GitHub issue links grouped by task ID.
• Manual-link and issue-watch metadata resolve to the same owner/repo/number key.
• Invalid metadata and tasks from other workspaces do not produce links.

Verification

cd apps/backend && rtk go test ./internal/github/...
