Story/jwill9999 cli polish

[jwill9999]

• UI/theming: add banner, palette, styled help (banner + examples), REPL prompt/tips; non-stream answer header/footer
  Rendering: support bold/italic inline; keep streaming raw; md rendering for non-stream

• Spinners: add “Thinking” indicator for ask (non/stream) and REPL (non/stream; stream until first token)

• Models: add listModels API and shared/models (TTL cache + fuzzy via Fuse); new models [query] cmd (interactive autocomplete in TTY, table fallback); integrate picker into init (OpenRouter-only), stable suggest mapping

• Enquirer: robust prompt resolution for ESM/CJS; fix autocomplete choice mapping; avoid debounce spinner conflicts

• Defaults: ask format=md and non-stream by default; REPL format=md and streaming off by default

• Error handling: add file logger (~/.config/openrouter-cli/cli.log), top-level friendly error message; REPL logs errors with context

• CLI polish: NO_COLOR/TTY-aware colors; help/tests updated

• Tests: add models.spec (fuzzy + cache), help-style, ui-answer; all green

• Docs: add existing_structure.md

• Chore: add TODO.local.md (ignored), expand .gitignore; ESLint TS unused-vars rule

BREAKING CHANGE:

• ask now defaults to non-stream and md rendering; pass --stream to stream
• REPL starts with streaming off and md for non-stream outputs; toggle with /stream on|off, /format md|plain
