Merge origin/main — unite all work onto one branch

Brings in dev log (NavLogger), UnitPrefs, MapLayerManager, HUD views,
conditions throttling, track save/load pipeline, improved ParticleWindView
(antimeridian-aware, dynamic particle count), Snackbar error surfacing,
and all other main-branch work from the prior session.

Combined with master's hardware source flags, vessel registry, crew
management, thermal alarm, CPA collision alerts, and track stats.

Also documents primary branch policy in CLAUDE.md and .agent/config.md:
all work merges to main, never master.
