alex 8dda49cfae lane J: the combat resolver, read from the instruction stream
Closes lane K's #1 ranked gap: FUN_007d5af0 under phase 6 of
OnAllCombatDone_Tail, the second RNG source in the strategic tail.

RNG inventory (the deliverable that matters). The resolver draws nothing
itself. Three sites in its subtree, each behind a function with exactly
one caller:

  R1  RNG_NextInt @0x007bb69b (node cannon)   1 word w.p. 3/4, mean 4/3
  R2  an INLINED RNG_NextFloat @0x007a84bd    1 word per back-eng candidate
  R3  RNG_NextInt @0x00852ec7 (project pick)  >=1 word per successful roll

R2 corrects combat-done-tail.md 3, which reported no NextFloat in the
subtree: the draw is inlined, so the only call-graph edge it leaves is
FUN_007a7f30 -> RNG_Twist, which reads as a bare Twist and is not one.
An image-wide instruction-boundary scan for the MT tempering immediates
finds 14 game functions with inlined draws; two of them, FUN_004f7670
(84 B) and FUN_007aa240, are reachable from StrategyServer::ProcessTurn
and are candidate mechanism for part of lane Z's unexplained 18-20
words per turn.

Also: the real body is 7641 B, not Ghidra's 7499 (which ends
mid-instruction); only 8 non-stack stores and 1 indirect call in the
whole function; 23 EVENT_* keys in the closure, five of them new to the
campaign's combat picture (plague is decided inside combat); the
resolver's subtree DOES write the SETurnResults accumulator at
S+0x2f4[PlyrIdx]+0x90 via FUN_007baef0 -> FUN_007b9df0; and
sizeof(Game::TacReport) = 0x94, enumerated twice.

Two structural errors made and corrected before publication are recorded
in 7.3 and 4 rather than quietly fixed.

Gates run separately: clean-room check OK; host ctest 36/36.
