Subject: Rename LabDAQ → LabUI and overhaul plugin system
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Branding:
- Rename app, window title, file extension (.labdaq → .labui), user data
  dirs (~/.labui/), spec file (labdaq.spec → labui.spec), and APP_NAME
  throughout all source, docs, and config files

Plugin system:
- Plugins no longer bundled in the PyInstaller build — installed at
  runtime by users via Settings → Plugins → Install Plugin (zip)
- PluginManager now takes user_dir + extra_scan_dirs; user plugins live
  in ~/.labui/plugins/, dev scan additionally covers project plugins/
- install_from_zip / uninstall / is_user_installed added to PluginManager
- vendor/ dir inside plugin zips: prepended to sys.path at load time so
  plugins can ship their own deps without requiring pip on end-user machine
- source_url field in manifest.json: shown as Download button in the
  missing-plugins dialog when a profile requires an absent plugin
- Frozen-app pip install now targets ~/.labui/plugin_packages/ using a
  real system Python (sys.executable is the exe in frozen builds)

Profile loading:
- Profile now stores plugins_manifest snapshot (id, name, version,
  source_url) alongside plugins_enabled
- On load, missing or dep-broken plugins trigger MissingPluginsDialog
  before the rest of the profile is applied; user can install from zip
  or download via source_url in-dialog, or cancel the load
- Plugin reconciliation only enables installed plugins — missing ones
  are not written to enabled.json

UI:
- Version label added to status bar (bottom-right, muted colour)
- Settings → Plugins tab: Install Plugin… button, per-plugin Remove
  button for user-installed plugins, live list refresh after install/remove

Docs:
- New docs/building.md covers the full release pipeline
- docs/plugin-development.md updated for new install flow, vendoring,
  source_url, profile behaviour, and distribution instructions
