KB: code-first sweep of stub/stand-in claims -> 2 more STALE fixed

Targeted pass on "stand-in / not-wired / stub / no-op" claims, verified against
CODE + runtime (not KB wording -- the trap that hid the peer-warp staleness):

- combat-damage.md STEP-6 "remaining = fix ResourceFindByName no-op -> empty
  table" (reads present-tense above the "STEP 6 COMPLETE" header): STALE. The
  table LOADS live ([cyl] table 'bhk1'/'madcat'/'ava1' layers=7); the name-load
  BYPASSED the no-op ResourceFindByName via SearchList(type=0x14) (mech.cpp:1631).
  d07ac7d. ResolveHit resolves unaimed hits.
- multiplayer.md "Mech::Reset full subsystem-reset sweep is still a bring-up TODO":
  STALE. mech4.cpp:1616 loops every subsystem -> DeathReset(mode) (heat/power/ammo/
  charge) + heals zones + ForceUpdate(0x1f). Per-subsystem DeathReset bodies are
  authentically trivial for some classes -- not a missing sweep.

Verified ACCURATE (not stale, left as-is): GaussRifle FireWeapon no-op (a decomp
fact -- inert in the 1995 binary; btl4gau2 faithfully marks it "not yet supported");
StatusMessagePool NULL stub (kill ticker live, non-kill status messages genuinely
deferred); Myomers coupling inert (genuinely open); searchlight fog-swap (open by
decision). checkctx CLEAN.
