Two root causes for issue #879:
1. GhosttyNSView was missing makeBackingLayer(), so AppKit provided a
generic CALayer as the view's backing layer. libghostty expects
(view.layer as? CAMetalLayer) != nil to set up Metal rendering on
the existing layer. Without a CAMetalLayer backing layer, the Metal
surface defaulted to isOpaque=true, making the terminal area fully
opaque regardless of background-opacity config.
Fix: override makeBackingLayer() to return a CAMetalLayer with
isOpaque=false and bgra8Unorm pixel format (matching standalone
Ghostty's SurfaceView behavior).
2. ghostty_set_window_background_blur(app, window) is exposed in
ghostty.h but was never called in cmux. Without this call the
macOS window never gets the NSVisualEffectView blur backdrop that
background-blur requires.
Fix: add applyWindowBlurIfNeeded() on GhosttyApp that reads
background-blur from config via ghostty_config_get and calls
ghostty_set_window_background_blur when the value is non-zero.
Called from applyBackgroundToKeyWindow() and
applyWindowBackgroundIfActive() whenever the window is made
transparent.

* fix: skip Korean from CJK font-codepoint-map auto-injection
The automatic CJK font-codepoint-map injection (PR #1017) maps Korean
ranges to Apple SD Gothic Neo, which has a different style/weight from
the primary terminal font. This overrides Ghostty's native
CTFontCreateForString fallback, which dynamically selects a
better-matching font for Hangul.
Ghostty itself (ghostty-org/ghostty) has no hardcoded CJK font names
and relies entirely on CTFontCreateForString for fallback. For Korean,
this native fallback produces visually consistent results with the
primary font.
Remove the Korean branch from cjkFontMappings() so Ghostty's native
fallback handles Hangul rendering. Japanese and Chinese mappings are
unaffected.
* test: update CJK font mapping tests for Korean removal
- testCJKFontMappingsReturnsAppleSDGothicNeoWithHangulForKorean
→ renamed to testCJKFontMappingsReturnsNilForKoreanOnly
→ asserts nil since Korean is no longer auto-mapped
- testCJKFontMappingsMultiLanguageMapsScriptSpecificRanges
→ renamed to testCJKFontMappingsMultiLanguageSkipsKorean
→ asserts no Apple SD Gothic Neo mapping exists
→ Japanese mappings remain unchanged

* Show update-available banner automatically on launch
Probe for updates immediately on launch via Sparkle's
checkForUpdateInformation() so the sidebar surfaces a passive update
indicator without waiting for the 24h scheduler. When Sparkle detects
an available update in the background, the pill now shows
"Update Available: X.Y.Z" with accent styling while the updater is
idle. Clicking it triggers the full interactive update flow.
Also fixes thread safety in delegate callbacks by dispatching
@Published mutations to the main queue.
Closes#1643

* Add periodic background update probe every 15 minutes
The launch-only probe wouldn't catch updates published while the app
is already running. Add a repeating 15-minute timer that calls
checkForUpdateInformation() so the sidebar banner appears within a
reasonable window after a new version is published.

* Change background update probe interval to 30 minutes

* Change update check interval to 1 hour and migrate existing users
Reduce Sparkle's scheduled check interval from 24h to 1h so update
banners appear sooner. Migrate users stuck on the old 24h default by
bumping the migration key to v2. Align background probe interval with
the Sparkle check interval instead of hardcoding 30 minutes.

The synchronizeScrollView() method was constantly resetting the scroll
position to match the terminal's scrollbar state, even when the user had
manually scrolled up to review scrollback. This caused the 'doomscroll'
bug where panes would fight the user's scroll position.
- Add userScrolledAwayFromBottom flag to track scroll intent
- Only auto-scroll when at bottom or when scrollbar indicates following
- Reset flag when user scrolls back to bottom
- Add 5-point threshold to tolerate minor float drift

ensureApplicationIcon() was explicitly loading and setting the light icon
via NSImage(named: NSImage.applicationIconName) even in automatic mode,
overriding the asset catalog's appearance-based icon selection.
Delegate to AppIconSettings.applyIcon() which correctly sets
applicationIconImage = nil for automatic mode, allowing macOS 15+ to
select the dark variant from the asset catalog automatically.
