Subject: [PATCH] chore(lint): forbid local withTimeout copies (#457)

Add no-restricted-syntax rule that bans:
- FunctionDeclaration named withTimeout
- VariableDeclarator named withTimeout initialized with a function or arrow function

Allow the canonical implementation in lib/with-timeout.ts via overrides.

Closes #457
