Rename project to Karvon

- Bundle identifier: uz.blaze.app-orchestrator → uz.blaze.karvon
- Crate / npm package name: app-orchestrator → karvon
- macOS app product name: "App Orchestrator" → "Karvon"
- All documentation, README, scripts, and configs updated.
- Migration: storage.rs's migrate_legacy_app_config_if_needed now walks a list
  of legacy identifiers (uz.blaze.app-orchestrator, dev.local-project-orchestrator.app)
  and copies the richest one it finds, so upgraders keep their projects, processes,
  and deploy history. The runtime pids file is migrated alongside.
- scripts/desktop-install.mjs: legacy app + bundle id chained to
  uz.blaze.app-orchestrator / "App Orchestrator.app" so an upgrade-in-place
  cleans the old /Applications copy. Process probe match updated for the new
  binary name "karvon".
- scripts/tauri-build.mjs: signing-key candidate list grew to karvon.key,
  app-orchestrator.key, local-project-orchestrator.key (first existing wins).
