Silere Shell 0.5.0

Upgrading: re-run the installer. Matugen now writes
$XDG_CONFIG_HOME/matugen/silere-shell.json instead of a file inside the checkout,
and until your config.toml points there, wallpaper colours stop changing and the
shell falls back to its bundled palette. If that file has an unpaired
# silere-shell marker the installer declines to touch it and says so; repair the
pair, then re-run.

Added

• Include AUR packages toggle under Settings › System › Updates, counting
  updates through paru or yay when one is installed. On by default. Checks stay
  read-only and never install anything.
• Settings › Theme and Settings › System › Maintenance now name whether Matugen is
  missing or has simply not written a palette yet, instead of presenting the
  bundled colours as if they came from the wallpaper.

Changed

• Matugen palettes live-reload from a user-writable JSON file, which also makes
  read-only packaged installs work.
• Text no longer scales on hover or press. A scaled glyph is drawn at one size and
  resampled to another, which softened labels on fractionally scaled outputs.
  Surfaces still react; the text on them stays put.
• Text renders with distance fields rather than snapping to a device pixel grid
  that fractional scaling has already resampled away.
• Buttons, pills, chips, toggles, media controls and slider handles share one hover
  and press response, quicker in than out.
• The bundled fallback accent is Silere's own default accent rather than white, so
  a system without Matugen looks like a fresh install rather than a stark one.
• Renamed the theme Source option from Neutral to Custom, and the accent picker's
  custom swatch to Mix, so the two no longer share a name.

Removed

• Keyboard navigation and its accessibility metadata. Tab order, arrow-key
  stepping, focus rings, the settings sidebar's keyboard cursor and every
  Accessible role, name and description are gone; the shell is pointer-driven.
  Escape still steps back and closes, scrolling works everywhere it did, and the
  Wi-Fi password field still takes typed input. Screen readers can no longer
  describe the shell.

Fixed

• A saved Wi-Fi network whose password had changed could not be reconnected. The
  row reconnected from the stored key, and once that key was refused, tapping again
  only repeated it — there was no way to enter a new one. A refused key now offers
  a retype, and the reason NetworkManager gave is no longer discarded, so a wrong
  key reads as Wrong password instead of Failed.
• The installer refused nothing on an unsupported session: a GNOME, KDE or sway
  user could install every file successfully and only find out at the autostart
  step, worded as a missing Hyprland config. It now names the compositor it found
  and asks before writing. A Hyprland or niri config on disk still counts, so
  installing before the compositor is up keeps working.
• scripts/install.sh ignored unrecognised arguments and started a real install,
  so --help installed instead of explaining. It now prints usage, and an unknown
  option exits 2 without writing anything.
• The media visualizer and track marquee froze on the only visible bar whenever
  focus moved to a monitor with the bar disabled.
• The screenshot watcher respawned every 60 seconds forever when no screenshot
  directory existed, instead of giving up on a failure restarting cannot fix.
• Notification history mislabelled days after a daylight-saving change, where a
  23-hour day put every entry one bucket early and produced two Yesterday
  headings.
• A hung update check, package check or VPN lookup now recovers through one shared
  bounded-process timeout instead of three hand-rolled timers.
• Optional-tool and font detection refresh cleanly at runtime.
• The workspace and window models no longer rebuild for a compositor event
  carrying nothing they read; it fired 420 times in two hours of ordinary use.
• Changing the clock's date style, or middle-clicking the clock, wrote the settings
  file twice in a row.
• The first settings section opened in a session no longer stutters compiling every
  shared control before it can draw.
• Settings row names keep a readable floor when space runs short; the value
  shortens first.
• Dropdown options and the Wi-Fi and Bluetooth list placeholders sat 4px shorter
  than neighbouring rows above 100% interface scale, putting dividers off the
  shared rhythm.
• The Wi-Fi password field is marked sensitive to input methods, so an IME or
  on-screen keyboard no longer capitalises the first character of a case-sensitive
  key or keeps it in predictive-text history.
• The settings panel eases to its new height when a category collapses instead of
  snapping.
• The palette card no longer bulges while switching theme Source between Custom and
  Wallpaper.
• Corrected the generated Cava profile's smoothing range.
