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 🤖 Generated with assistance of https://github.com/code-yeongyu/oh-my-opencode * feat(ralph-loop): integrate ralph-loop and cancel-ralph command handlers into plugin hooks - Add chat.message hook to detect and start ralph-loop or cancel-ralph templates - Add slashcommand hook to handle /ralph-loop and /cancel-ralph commands - Support custom --max-iterations and --completion-promise options 🤖 Generated with assistance of https://github.com/code-yeongyu/oh-my-opencode --------- Co-authored-by: sisyphus-dev-ai <sisyphus-dev-ai@users.noreply.github.com>
