feat: add a native CLI launcher for local and YouTube playback

Build .build/terebi beside the app. Parse a single local file or YouTube URL, --url, --, and help; reject invalid commands before GUI launch. Resolve the adjacent app through symlinks and launch through NSWorkspace, reusing its process/window and saved progress. Launch the app without media before delivering URL events. Raw media argv suppress SwiftUI's initial singleton window. Own warm document and internet Apple events because SwiftUI's default external-event routing closes that window; retain initial Finder document delivery to create it. Verified actual CLI 0/64/69 exit behavior, PATH/symlink discovery from another directory, cold local/YouTube playback, warm local/YouTube replacement in the same native window/process, resume, Finder-style cold launch, and make all check.
