Merge remote-tracking branch 'langbot-app/master' into feat/sandbox

Resolve conflicts in:
- .github/workflows/run-tests.yml: keep master's src/langbot/** paths plus feat/** push branch
- src/langbot/pkg/plugin/connector.py: keep both branches' marketplace MCP/skill
  install logic (HEAD) and runtime/wait helpers (master); add missing return in
  _inspect_plugin_package so LOCAL/GITHUB install paths get author/name back
- tests/unit_tests/pipeline/test_n8nsvapi.py: keep HEAD's try/finally sys.modules
  save/restore pattern
- web/src/app/home/components/dynamic-form/DynamicFormComponent.tsx: union
  imports + keep HEAD's disable_if/tooltip support and master's QrCodeLoginDialog
- web/src/i18n/locales/*: union of disjoint top-level keys from both branches
- web/src/app/home/market/page.tsx: accept our deletion (unified extensions page)
- uv.lock: regenerate via uv sync --dev
