Loudini v0.3.0

Added

• Render-stall watchdog — the daemon now watches its own render heartbeat.
  If the audio pipeline goes quiet while apps are playing, it tears the tap down
  so sound returns to the direct path instead of leaving you in silence, then
  rebuilds. status.json reports reason: "render stalled" while it recovers.
• Automated tests — 55 contract checks over the control/status file
  (scripts/test.sh), run on every push. They pin the invariants that matter:
  per-app overrides survive a master-only write, a malformed file keeps the last
  good value, gains clamp to 0–100, and a dead daemon can't claim running:true.
• scripts/make-dev-cert.sh — one idempotent command for the stable
  "Loudini Dev" signing identity, so TCC grants stop resetting on every rebuild.
• scripts/bump-version.sh — writes the version to all five files that
  carry it, instead of five hand edits.

Fixed

• The menu named the wrong fix for Background Music: the daemon and the menu-bar
  app kept separate lists of conflicting apps and had drifted apart. Both now
  read one shared list (helper/Conflicts.swift).
• Sharing a link to loudini.app showed no preview image, and the page's canonical
  URL pointed at the old github.io address.

Changed

• Releases now fail fast. A preflight asserts the five version homes agree, that
  no version is hardcoded in the packaging script, and that these release notes
  are actually written — in seconds, before the build and Apple's notary queue,
  rather than an hour into it.
• Re-running a release no longer re-buys work Apple already accepted: a stapled
  app is reused when it matches the current sources, and an interrupted DMG
  notarization resumes instead of re-uploading.
