feat: add sidebar panel, i18n, token validation, and UX improvements

- Add sidebar.js: full actionable sidebar panel with 6 GitHub operations
  (Open Repo, Open Gist, Delete Gist, Delete Gist File, Update Token, Clear Cache)
- Add Chinese/English i18n based on device locale detection (navigator.languages)
- Token handling: normalize input (strip Bearer/token prefix, trim whitespace),
  validate format, and immediately verify against GitHub /user API on save
- Enhanced API error messages: include GitHub's response message and documentation URL
- Fix stale gh:// filesystem handlers from old plugin instances via global registry
  pattern (window.__acodeGithubFsTests__) for proper cleanup across plugin reloads
- Prefetch repos/branches before opening palette to avoid misleading empty results
- Show toast after opening repo folder guiding user to check file browser sidebar
- Pass listFiles:false to openFolder to skip 'list all files may crash' prompt
- Localize all user-facing strings: tutorial, commands, dialogs, toasts, settings
- Update .gitignore to exclude pem files, debug server, and package-lock.json
