Changes

PERF-01: one TwinBroadcaster task propagates the catalog once per tick and fans the same payload out to every connected client (was per-client propagation).
CORR-06: apply Greenwich sidereal rotation before converting ECI longitude for Cesium.

Tests

tests/test_twin_ws_fixes.py: catalog propagated once for all clients, clients share one background task, longitude rotated to Earth-fixed.

Not verified

Not exercised against a live WebSocket/Cesium frontend.

Verification

Full suite with the new tests passes locally on this branch (25 existing + new tests, pytest on Windows, Python venv).
py_compile clean; ruff fatal-error lint (E9,F63,F7,F82) clean.
Does not touch files owned by open PRs Move Cesium token, API key and DB DSN to environment variables #1-Fix HIGH correctness bugs CORR-01..05 #5.

Drafted by Codex from the medium/low review findings; split and re-verified per branch.
