feat: add Ralph Loop self-referential development loop (#337)

* feat(config): add RalphLoopConfigSchema and hook name

- Add ralph-loop to HookNameSchema enum
- Add RalphLoopConfigSchema with enabled, default_max_iterations, state_dir
- Add ralph_loop field to OhMyOpenCodeConfigSchema
- Export RalphLoopConfig type

* feat(ralph-loop): add hook directory structure with constants and types

- Add constants.ts with HOOK_NAME, DEFAULT_STATE_FILE, COMPLETION_TAG_PATTERN
- Add types.ts with RalphLoopState and RalphLoopOptions interfaces
- Export RalphLoopConfig from config/index.ts

* feat(ralph-loop): add storage module for markdown state file management

- Implement readState/writeState/clearState/incrementIteration
- Use YAML frontmatter format for state persistence
- Support custom state file paths via config

* feat(ralph-loop): implement main hook with session.idle handler

- Add createRalphLoopHook factory with event handler
- Implement startLoop, cancelLoop, getState API
- Detect completion promise in transcript
- Auto-continue with iteration tracking
- Handle max iterations limit
- Show toast notifications for status updates
- Support session recovery and cleanup

* test(ralph-loop): add comprehensive BDD-style tests

- Add 17 test cases covering storage, hook lifecycle, iteration
- Test completion detection, cancellation, recovery, session cleanup
- Fix storage.ts to handle YAML value parsing correctly
- Use BDD #given/#when/#then comments per project convention

* feat(builtin-commands): add ralph-loop and cancel-ralph commands

* feat(ralph-loop): register hook in main plugin

* docs: add Ralph Loop feature to all README files

* chore: regenerate JSON schema with ralph-loop config

* feat(ralph-loop): change state file path from .opencode to .sisyphus
