Weapon visuals + aim: beams render from the guns; pick self-target fixes

Browse Source 
Renderer (dpl3-revive/patha):
- Instance visibility honored at DRAW time (stored word 4 = live
  dpl_SetInstanceVisibility field): laser beams (4-frame pulses) and
  missile models now render; cache tags w3 0/1 instances 'gated'
- PSFX world bursts (dcs=0 muzzle/impact/explosion) rendered; psfx
  storage list-based so one-shot bursts stop collapsing onto one key
- fix_degenerate applied to INSTANCE chains (was camera-only): the
  beam chain rides four rank-2 rig DCSs; composed rank-2 drew beams
  away from the guns. Offline f1635 now shows both arm beams
  converging on the aim point
- First-person canopy cull: the always-armed cockpit model at the
  head drew as a vertical line down screen center (user-confirmed
  fixed live)

Device (vpx-device/vpxlog.cpp):
- CAM backchannel on the fifosock: bridge streams its validated
  camera (+ vehicle root DCS); raycast_pick aims along the player's
  real look instead of the static view-node pose, which had locked
  every missile/beam onto one fixed wrong world point
- raycast_pick skips hidden-until-armed instances and the player's
  own articulation subtree: picking own beams created a target
  feedback loop, picking own missiles retargeted salvos mid-flight,
  and a picked missile's deleted DCS froze the game (arena2 crash)

Sound (vpx-device/vweawe.cpp): stereo-linked peak limiter replaces
the hard output clamp (the "generator out" crackle); VWE_AWE_LOG
reports pre-limit peaks + duck counts, enabled in launch_pod.ps1.
Missile-fire crackle persists: per-voice EMU8000 clamp suspected.

Eggs/confs: TESTAR2.EGG + gauge_arena2_sound.conf (map=arena2 city
variant); cavern.egg (console-era reference); plasma display on COM2
in the gauge confs; gauge_arena_net_sound.conf (slirp net stack).

"""Triggered PSFX (0x1d) as glowing additive discs, two kinds:
- DCS-attached bolts (weapon fire): the emitter rides the flying
projectile DCS, so the glow tracks the shot. We keep a short trail of
recent world positions and draw a fading tail, so the continuous
particle stream (rate ~300/s) reads as a streak, not a lone dot. The
bolt lives until the projectile DCS is deleted (impact).
- DCS=0 world bursts (muzzle flash, impact spark, explosion): a fixed
world-space burst at (px,py,pz); big-radius explosions expand and the
colour lerps from the start interior toward the end interior over the
burst's ttl, then it fades out."""
