Summary

Add an opt-in Hide bar on fullscreen setting for overlay bars on niri. When the active window on an output enters fullscreen, DBar slides the top bar away with its existing auto-hide animation. It slides back on exit. The theme controls transition duration, including disabled animations, and the pointer can reveal the hidden bar from the screen edge.

The setting defaults to off and requires Use overlay layer. It does not enable global auto-hide or change the bar's layer. Fullscreen-only hiding keeps the configured exclusive zone, so it does not cause other windows to relayout on entry or exit. Existing global auto-hide still releases the zone as before. Frame-hosted bars, islands, and other compositors are unaffected.

This is the Dux 2.0 DBar port of #3335. It incorporates the earlier review fixes:

• Clear IPC reveal state when effective auto-hide ends, so a previous bar toggleReveal does not prevent the next fullscreen hide.
• Use effective auto-hide for edge-hover input even when global auto-hide is off.
• Preserve the exclusive zone when fullscreen hiding is the only active hide policy.

Niri IPC and Wayland toplevels have no shared window ID. Matching uses exact app ID and title on the output, with keyboard focus as a disambiguator. If a match remains ambiguous, the bar stays visible.

Validation

• node --test quickshell/tests/bar-ipc.test.mjs quickshell/tests/niri-workspace-state.test.mjs: passed after the review changes.
• make test-qml: Qt 31 passed, lock 38 passed, logic passed before the review changes.
• Patched dux-shell 2.0.0-3 built and installed locally before the review changes. A plain dms restart loaded the embedded patch. Fullscreen entry and exit were checked in a single-monitor niri session, and the user confirmed the behavior works.
• git diff --check: passed.

The exclusive-zone behavior has not been measured live. Pointer-edge behavior and physical multi-monitor behavior have not been checked separately on Dux 2.0. make lint-qml could not run in the fresh worktree because Quickshell's VFS .qmlls.ini had not been generated.
