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.
Extract Gabe Emerson's Trav'ler rotor scripts into a proper Python
library with firmware protocol abstraction (HAL 2.05 + HAL 0.0.00),
Hamlib rotctld TCP server, Click CLI, and isolated leap-frog algorithm
with the elevation copy-paste bug fixed.
