Remove hook execution timeouts

- Remove timeout logic from HookRunner
- Remove hookTimeout from Settings interface
- Remove getHookTimeout/setHookTimeout methods
- Update CHANGELOG.md and hooks.md

Timeouts were inconsistently applied and caused issues with
legitimate slow operations (LLM calls, user prompts). Users can
use Ctrl+C to abort hung hooks.
