- Restore full Ink TUI startup chain (cli.tsx entry point)
- Create stub .md files for verify skill (Bun text loader hang fix)
- Create stub types for filePersistence and SDK modules
- Fix Enter key not working (modifiers-napi missing, added try-catch)
- Remove overly conservative LOCAL_RECOVERY early return
- Add README with setup instructions
- Add .env.example template
- Add bin/claude-haha entry script and preload.ts
