Rename project from travler-rotor to birdcage

The radome looks like a birdcage, ham operators call satellites
"birds", and it's a nod to saveitforparts saving dishes "for parts."

Package, CLI entry point, class names (BirdcageAntenna), env vars
(BIRDCAGE_PORT, etc.), and CLAUDE.md updated. Hardware references
(Winegard Trav'ler, Trav'ler Pro, Carryout G2) unchanged.
