* fix(linux): AppImage registers its desktop entry and icon on launch
On Wayland the compositor resolves the dock icon from the window's app_id
(ai.storyteller.photocraft, already set) against a host-installed .desktop
file. An AppImage installs nothing, so every run showed the generic Wayland
logo (#593). The app cannot set the icon itself: winit 0.30.13 (egui 0.36.2's
pin) has an empty set_window_icon on Wayland; xdg-toplevel-icon-v1 landed on
winit's 0.31 line only.
- packaging/linux/AppRun is a script instead of a symlink: best-effort
integration into $XDG_DATA_HOME before launch (desktop entry with Exec
rewritten to the AppImage's path and TryExec dropped, hicolor icons
copied), content-compared so an unchanged install costs a few cmp calls,
refreshed when the AppImage moves, PHOTOCRAFT_NO_DESKTOP_INTEGRATION=1
opts out, and no failure can block the launch (best-effort steps silent).
- packaging/linux/apprun-test.sh: 8-case smoke (passthrough, Exec rewrite
with spaces, metadata preserved, idempotence, move refresh, opt-out,
unwritable data dir, extracted AppDir). packaging-lint runs it and now
shellchecks AppRun.
- Docs: releasing.md Linux section; README install paragraph.
Fixes#593
* AppRun: skip desktop integration when the AppImage path needs Exec escaping
A quote, backquote, dollar, backslash, percent or line break in the path would need
desktop-entry escaping (a line break could even add keys), so integration is skipped
and the app still launches.
