feat(config): add disabled_hooks option for selective hook disabling

Allow users to individually disable built-in hooks via the
`disabled_hooks` configuration option in oh-my-opencode.json.

This addresses issue #28 where users requested the ability to
selectively disable hooks (e.g., comment-checker) that may
conflict with their workflow.

Available hooks:
- todo-continuation-enforcer
- context-window-monitor
- session-recovery
- comment-checker
- grep-output-truncator
- directory-agents-injector
- directory-readme-injector
- empty-task-response-detector
- think-mode
- anthropic-auto-compact
- rules-injector
- background-notification
- auto-update-checker

Closes #28
