momPanel v0.5.0

Added

• Companion mode (experimental preview). A reimagined, status-by-exception panel
  (src/preview/companion.js/.css): a greeting and giant clock, the weather as the
  hero with a 4-day strip, and a single "All is well" health card (Internet / Wi-Fi /
  Printer / Sound / Speed / Space) that surfaces plain-language attention cards — with
  the right settings button — only when something needs attention. The background sky
  shifts with the time of day. Toggled in About → Preview (experimental_ui in
  config; the app reloads on switch). Same collectors, same cadences; DOM is patched
  in place, never rebuilt on a timer.
• Remembered window position. WindowEvent::Moved persists the outer position
  (throttled to ≥2s, flushed on close) to new window_x/window_y config fields and
  restores it via set_position before the now-created-hidden window is shown.
  Best-effort on GNOME Wayland (the compositor ignores client positioning); effective
  on X11 and Windows.
• Single instance. tauri-plugin-single-instance, registered first in the builder;
  a second launch shows/unminimizes/focuses the running panel instead of spawning a
  duplicate process — important for an app that autostarts on login.
• CI. .github/workflows/ci.yml runs cargo test + cargo check on PRs and
  pushes to main — the first automated Linux compile check for cfg(linux) code.

Fixed

• Locale-proof collectors. Every parsing subprocess spawn (nmcli, lpstat,
  wpctl) now pins LC_ALL=C/LANG=C. Previously the parsers matched English
  literals, so on any non-English system Printers listed nothing and Wi-Fi read
  "unavailable" while connected.
• Stale-response race. The tile loop tags each fetch with a generation and
  discards out-of-order responses — a slow 20s poll can no longer repaint "Offline"
  over a fresh D-Bus-pushed "Online" after a reconnect.
• First-run ZIP prompt lifecycle. Opening a new prompt cleanly resolves the
  previous one (no hung promise, no leaked document keydown listener), and the
  automatic prompt fires once per session instead of on every window focus after a
  cancel. The explicit set/change-location affordances still always prompt.
• Modal hygiene. A shared src/modal.js closes the active overlay before another
  opens (no stacked keydown listeners), and .modal-backdrop now layers above the
  bottom-right control pill (the "i" button was clickable through the backdrop).
• Clock/date rebuild churn. Both tiles patch their DOM in place instead of
  innerHTML-rebuilding every second — the analog/digital toggle keeps focus and hover,
  and the month calendar rebuilds once a day, not 86,400 times. The analog second hand
  is omitted under prefers-reduced-motion (previously claimed, not implemented).
• Weather robustness. A failed refresh keeps the last good forecast on screen with
  an "as of" time; the ZIP geocode is cached in config and Open-Meteo's geocoding API
  backs up zippopotam.us (no longer a single point of failure); one shared reqwest
  client instead of a fresh TLS setup per fetch; a missing ZIP shows a friendly
  "Set up weather" button instead of a dead tile.
• Memwatch efficiency. The watcher reloads config only when a save-generation
  counter changes (was: read + parse config.json from disk every 2 seconds,
  forever). Config writes are atomic (tmp + rename) and serialized so overlapping
  saves can't drop a patch or expose half-written JSON. Alert tone/speech play on a
  detached thread so the poll loop keeps ticking during playback.
• Internet probe. The TCP reachability verdict is cached for 20s and tries 443
  before 53 (some networks block outbound DNS to Cloudflare).
• Gauges no longer render a stray colored dot at 0% (round linecap on an empty arc);
  storage reports decimal GB to match GNOME Files/Disks; the What's New card caps
  its height and scrolls (a long release note pushed "Got it" off-screen); theme
  colors — including High contrast — now reach the internet globe, Wi-Fi arcs, and
  printer dots; muted volume shows a big crossed speaker and "Sound is off"; the
  size control clamps to the monitor (font + window shrink together) and no longer
  re-centers the window on a size change.

Changed

• Dead src/mock.js removed (it was imported nowhere); package.json version aligned
  with the app version; libappindicator3-dev dropped from the release workflow (no
  tray icon).
