MP live-play wave: collision economy, missiles, radar transform, panel polarity, comm ticker

The interactive 2-node playtest wave -- every fix decomp-grounded and live-verified:

COLLISION ECONOMY (the ram one-shot): StaticBounce mutates worldLinearVelocity
per contact and ProcessCollisionList walks EVERY touched solid per frame; with
2007 terrain-as-solids the reflections compounded x4-x40 within one frame and a
walking bump one-shot a pristine mech for 112,375 pts (62-pt authentic economy).
Fix: frameEntryWorldVelocity restore per contact (damage always priced at the
real approach speed -- all the binary's physics ever saw); Mech::Reset zeroes
the mover motion (respawn = teleport); [collide-tx]/[mp-hdlr] telemetry.
Gotcha #16 (engine-facility drift class).

MISSILES: peer-visible salvos (the launcher record extension carries a salvo
counter + aim point; ForceUpdate actually enqueues it -- the dirty flag alone
never serialized), the authentic arc (authored MuzzleVelocity vector + the
Seeker's 200m/0.1/300 loft + gain-4 steering, decoded from @004beae4/@004bef78),
world-impact bursts (rounds detonate on cave geometry instead of phasing
through), contact-only damage (flight-cap expiry = fizzle, no more teleport
damage), live re-lead, and ballistic (unguided) shells for autocannons.
projweap's stale BTPushProjectile extern (the /FORCE signature trap, gotcha #6
corollary) crashed the Avatar's first AFC100 shot -- fixed + sweep rule recorded.

RADAR: two transcription bugs made the scope permanently empty -- FUN_0040b244
is the affine INVERSE (not a copy) and FUN_0040adec writes ONLY the 3x3 rotation
(never the translation); worldToView now Invert(view) built rotation-first.
CulturalIcons sorted out of the moving grid (the phantom red pips were map
props), visible-radius culls on all three draw passes, live pip verified at
|delta| x ppm px.  Gotcha #17 (verify the FUN_ body, not its call shape).

WEAPON PANELS (the frozen-dial hunt): the binary's *(subsystem+0x40) means
FAILED -- the recon's 'operating' name was backwards, inverting the destroyed-X
lamps, the panel look, the children enable and the ready-lamp gate (which had
NEVER executed).  Polarity chain corrected end-to-end (failedState, fed by real
damage saturation).  Root cause of the freezes: MFD page-mode gating -- the dev
composite shows ALL pages at once, so off-page dials legitimately stopped; under
BT_DEV_GAUGES the 15 page-plane bits stay active (the exclusive secondary trio
untouched).  The SEH gauge guard now names its kills; repaint-heal resets the
incremental arc after panel repaints; [panel]/[arc] probes added.

COMM/SCORE: MessageBoard LIVE (the engine already shipped the whole
Player__StatusMessage queue; wired the binary's one producer -- the kill branch,
victim's name, 6s -- plus the consumer bridge and a lazy source bind); MP DEATHS
counted via the observed-death tally (each node scores every pilot from locally
observed events, the same model as the KILLS credit) and the -2/-1 engine seed
clamped for display.

DEV UX: node-tagged window titles (-net port), gauge panel reworked (1320x480,
true 4:3 MFD cells, the portrait secondary UNROTATED upright, linear filtering,
BT_GAUGE_SCALE), fixed close spawns via BT_SPAWN_XZ, Boreas flies an Avatar
(first second-chassis live outing).
