Root cause: router.ts called generateWorkerCode() before passing to backend,
so backend always received 'code' (mode A) and never entered the requires
branch (mode B). Also stored original execute body in meta for clean dep
resolution instead of fragile regex extraction.
Fix:
- Router passes execute directly to backend, lets backend handle codegen
- Meta now stores execute field for dependency resolution
- resolveDependencies uses meta.execute (falls back to regex extraction)
Verified end-to-end:
- formal-greet(requires greet-name) → '[Formal] Hello, Scott!'
- xiaoju-github-repos(requires xiaoju-github-token) → real GitHub API response
