v0.23.0

• Audio pack. w-pack install audio sets up music production on W's
  PipeWire stack: Ardour 9, qpwgraph for routing, Audacity, and a plugin starter
  set (Surge XT, the LSP suite, Dragonfly Reverb). PipeWire takes over the JACK
  API — pipewire-jack replaces jack2, and stays if the pack is removed,
  because other apps link against it — and your account gets realtime audio
  priority from your next login. Ardour, Audacity and qpwgraph open in your W
  colours. The W assistant can work inside an open Ardour session — tracks,
  plugins, mixer, MIDI — once you turn on MCP HTTP Server (Experimental) in
  Ardour's Preferences → Control Surfaces; it is off by default because Ardour's
  server listens on every network interface without authentication. About
  660 MiB. The installer offers the pack as well.
• W Help. SUPER+F1, Hub → Documentation and the new Open in Help button
  on documentation cards now open the W documentation as a site in its own
  window: pages by category, search, English and Russian, painted in your
  current theme. It is the copy on disk in /usr/share/doc/w/html, so it works
  offline. From a terminal: w-help [page[#section]].
• Assistant, Calendar, Power menu and Volume control start from any app.
  Their launcher entries carried an escape that GLib rejects, so Nemo,
  gio launch and the desktop portals could not start them — only W's own
  launcher could. Fixed.
• Arrow keys in W dialogs moved focus the wrong way in rows of buttons.
  Fixed.
• Assistant: remote MCP servers. A drop-in in mcp.d can name its server
  with URL= (streamable HTTP) instead of COMMAND/ARGS; every assistant
  host receives it in its own native form.
• Signed install images. From the next nightly build the ISO carries a
  Sigstore build-provenance attestation, made by the build itself. Check it with
  gh attestation verify w-*-x86_64.iso --repo tarkh/w; the edge release
  notes show the steps.
• A broken link to the FAQ in Keeping W up to date (English and Russian) is
  fixed.
