Lane B prerequisite: take the data lane's hunks in six Lane B files

Identical text to claude/data-section-credit-20260920 for these six files
(git diff against that branch is empty), so the two branches merge cleanly.
ZERO Lane B credit is claimed: the five data sections belong to the data lane.

Taken deliberately because three of the hunks change relocation IDENTITIES
that Lane B code residuals need before they can ever gate exact:
  action_vehicle.c        0.1225f -> 0.35f*0.35f  (__real@3dfae147, January's
                          folded product) - _action_vehicle_find_destination
  collision_debug.c       assert text count<=14   - _collision_debug_render
  path_structure_bsp.c    assert spacing          - _structure_test_line2d
and three are the .bss layout law (= 0 / = FALSE on debug globals):
  player_control.c, collisions.c, bipeds.c

Units/functions: none change verdict. Strict meaningful +0, padded +0.
Fuzzy: none. Data: +489 B (116+300+43+26+4), credited to the data lane.
Stable regression: scratch/lane_b_before.json -> lane_b_w0.json, 0 regressions,
0 gains. Lane inventory row-diff: 0 losses, 0 moves. Parks 0 stale / 0 invalid.
Full ninja all_source progress semantic_progress: pass
(Code 1443979 / 1770166, 7291 / 7574; Data 2360994 -> 2361483).
Config/header changes: none. Reviewer: data lane's own verification; re-verified
here by full build and row diff.
