refactor(init): address PR #124 review feedback

[wyattjoh]

Summary

Follow-up to #124 addressing review feedback that landed after merge.

• Drop the commit-message-style comment above the runners import; the function docstring and import names already cover the contract.
• Simplify runFormatters to trust ctx.deps. gatherContext already calls readDeps, so the readDeps(ctx.cwd) fallback was dead code in practice and masked intent.
• Drop the silent try/catch blocks around Bun.spawn/which/spawnSync mock setters in format.test.ts. They swallowed mock-assignment failures; if Bun ever makes those properties non-writable, tests would run against real globals with confusing results. Now verify the assignment took effect and fail fast.
• Extract the Bun override cast once to cut boilerplate.
• Add a test locking in the best-effort behavior when a formatter exits non-zero (we intentionally ignore exit codes).

Test plan

• bun run test passes

📝 Walkthrough

Walkthrough

The changes remove disk-based dependency discovery from the formatter initialization logic. The production code (format.ts) eliminates the readDeps() call and adds an early return when ctx.deps is empty, forcing exclusive reliance on ctx.deps. The test file (format.test.ts) restructures its Bun API mocking to use a single typed bunOverrides view with explicit error throwing on failed assignments, replaces mock restore logic with direct reassignment, and removes test cases that depended on disk-based package discovery.
