bench parity: local nodes now launch exactly like a player's shortcut

Browse Source 
Local benches had drifted from the shipped launchers and every divergence
cost a debugging session:

  * no BT_START_INSIDE -> benches opened in the EXTERNAL CHASE camera while
    every player starts in the COCKPIT.  The first first-person look at a
    bench window was misread as a broken HUD.
  * novice bench eggs  -> every SHIPPED egg is expert; novice gates off the
    entire heat model, crits and jams, so bench combat was not field combat.
    (Verified: the aligned node now boots experience=3 simLive=1
    heatModelOn=1, where it used to boot 0/0/0.)
  * 1-LP affinity pins -> starved the gauge executive and produced a false
    "the comms panel never counts deaths" reading.  Two LPs per node keeps
    the documented single-box jitter fix without the starvation.

scratchpad/night6/bench_common.sh now owns the contract (bt_player_env,
bt_launch, bt_expert_egg, bt_novice_egg) copied verbatim from play_solo.bat,
with bt_assert_player_env warning if the shipped bat ever drifts.  All three
4-node benches source it.  The limp bench keeps a novice egg -- expert crits
the aimed leg and the mech turns-but-never-moves -- and now says so loudly.

Also: BT_SHOT_EVERY=<n> headless backbuffer capture (btl4vid.cpp), the tool
this was diagnosed with.  It must sit above the warp phase-0 early-out since
that fn is the per-frame alpha-pass hook.  OS screen-capture is off-limits:
a foreground-lock failure photographed the user's browser instead of the game.

KB: build-and-run.md gains the bench-parity rule + the capture diag;
cockpit-view.md gains the measured aspect/FOV finding (the surround's 2.05:1
view collapses vertical FOV to 31.5 deg vs the pod's 46.8, so fixed canopy
geometry covers 68.6% of the lower half -- NOT a regression: the shipped 643
binary reports identical geometry).
