Mech phase 2: reconstruct HUD (: PowerWatcher) -- Mech hudSubsystem

Head-up display / targeting reticle subsystem, full named member set (reticle/ compass/lock/flicker/torso-readout state). Ctor chains PowerWatcher + inits per the binary (visible/blinkState True, vectors zeroed, resource flicker/horizontal copied); statusAlarm.Initialize(2). Added AlarmIndicator::Initialize(levels). statics/dtor/test real; HudSimulation staged. BT: 29 ok. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
