Canopy

Added

• Native macOS notifications via UNUserNotificationCenter. Session-finished
  banners now show Canopy's app icon and name (instead of Script Editor's),
  and clicking a banner activates Canopy and selects the finished session's
  tab. (#3)
• Background update check on launch. A rate-limited (once per 24h) GitHub
  Releases poll surfaces update availability in the About sheet and Settings,
  with a manual "Check Now" button and a native notification when a newer
  release is found. Semver comparison is numeric (so 0.10.0 > 0.9.0). (#4)
• Help → Check for Updates... menu entry that triggers an immediate check
  and opens the About sheet so the status row is visible.
• Splash hero in the About sheet — a downscaled JPEG of the README splash
  image, with the About sheet resized to 540×520 to match the 2.4:1 aspect.
• Launch splash: the Canopy logo is now rendered in warm sand beige with a
  1px black outline, and the duplicate wordmark overlay on the About hero
  has been removed.

Fixed

• Resources/ directory (CanopyLogo.png, Canopy.icns, Splash.jpg) was
  being silently excluded from every Xcode build because project.yml used
  an invalid XcodeGen resources: target key. The app previously only
  worked because AboutView had a relative-path fallback. Resources are now
  bundled via a proper sources: entry with buildPhase: resources.
• NotificationService.swift was present on disk but not registered in
  Canopy.xcodeproj/project.pbxproj, which would have broken the next
  tagged release (xcodebuild archive does not do SPM-style target
  globbing). Regenerated via xcodegen.
• DMG no longer ships the xcodebuild -exportArchive sidecar files
  (DistributionSummary.plist, ExportOptions.plist, Packaging.log).
  create-dmg is now pointed at Canopy.app directly instead of the
  build/export/ directory.
• Update-available notification path no longer references the removed
  AppleScript helper (leftover from the update-checker merge) that was
  breaking the CI build.
• README "Build" badge now points at ci.yml instead of release.yml, so
  it reflects master status rather than only tag pushes.

Internal

• Homebrew tap workflow gained a workflow_dispatch trigger with a tag
  input, so the cask update can be re-dispatched on demand. The default
  GITHUB_TOKEN suppresses the cascading release: published event, so a
  manual escape hatch is required.
