fix: center shortcut key pill '+' separator between key caps

The renderShortcutDisplay function grouped each key cap and the '+'
to its right in a wrapper <span> with justify-content: space-evenly,
making the '+' appear closer to the left key cap. Flattened to
React.Fragment siblings in a flex row with justify-content: center
and gap: 4px so the '+' sits independently centered.

Also adds CHANGELOG and AUDIT_LOG entries for this fix and the
previously merged macOS window shift compensation removal.

-**Change:** fix: window state persistence and login-item toggle desync (v0.5.4)
+### 2026-06-25 - fix: remove macOS frameless window 28px shift compensation (PR #62)
+
+**Details/Why:**
+The v0.5.4 window-state fix incorrectly added +/-28px compensation for a supposed macOS frameless window titlebar offset in `tauri-plugin-window-state`. Tracing through the full stack (`tauri-plugin-window-state` v2.4.1 → `tauri-runtime-wry` → `tao` 0.35.3) confirmed no such offset exists for `decorations: false` windows — `outer_position()` returns the window frame origin and `set_position()` sets it correctly. Removed all compensation from save and restore paths.

+### 2026-06-25 - fix: shortcut key pill "+" centered between key caps
+
+**Details/Why:**
+In the Settings global shortcuts section, the `renderShortcutDisplay` function grouped each key cap and the `+` to its right in a wrapper `<span>`, with the outer container using `justify-content: space-evenly`. This made the `+` appear closer to the left key cap. Fixed by flattening to `<Fragment>` siblings in a flex row with `justify-content: center` and `gap: 4px`.

 ### Fixed
 - **Window position/size now persists across restarts**: The window-state plugin's `on_window_ready` fires before the macOS display server is ready, causing `available_monitors()` to return empty and the saved position to be silently discarded. Fixed by deferring window-state restoration via a background thread + `run_on_main_thread` 300ms after `setup()` completes, bypassing the plugin's monitor-intersection check with a direct file read. Both the tray "Quit" and Settings "Quit" buttons now explicitly save window state before exit.
 - **Launch at Startup now registers as a proper Login Item**: Changed `MacosLauncher` from `LaunchAgent` to `AppleScript`, which registers PaperCache in System Settings > General > Login Items instead of creating a hidden `launchd` plist. Users can now see and manage the autostart entry directly from System Settings.
+- **Window no longer shifts down on restart on macOS**: Removed the +/-28px compensation that was incorrectly added for a macOS frameless window offset which does not exist in `tauri-plugin-window-state` v2.4.1 — the plugin correctly saves `outer_position()` and restores via `set_position()` with no titlebar offset for frameless windows.
+- **Shortcut key pill "+" centered between key caps**: The `+` separator in the shortcut display was grouped inside the same `<span>` as the key cap to its left with `justify-content: space-evenly`, making it appear visually attached to the left pill. Restructured to a flat flex layout with `gap` so the `+` is independently centered with equal spacing on both sides.
 - **Login-item toggle stays in sync with macOS System Settings**: The launch-at-startup toggle only read from `localStorage`, so removing PaperCache from System Settings left the toggle permanently stuck in the checked state. Fixed by adding a `get_launch_at_startup` Tauri command that queries the actual OS login-item state via `app.autolaunch().is_enabled()`, and syncing the toggle with the real OS state on every Settings mount.
