Affaan Mustafa 7356fd996f refactor: extract inline PostToolUse hooks into external scripts
Move three complex inline hooks from hooks.json into proper external
scripts in scripts/hooks/:

- post-edit-format.js: Prettier auto-formatting (was 1 minified line)
- post-edit-typecheck.js: TypeScript check (was 1 minified line with
  unbounded directory traversal, now capped at 20 levels)
- post-edit-console-warn.js: console.log warnings (was 1 minified line)

Benefits:
- Readable, documented, and properly error-handled
- Testable independently via stdin
- Consistent with other hooks (all use external scripts now)
- Adds timeouts to Prettier (15s) and tsc (30s) to prevent hangs
