#188: the Jacquard selector's 64 cards, L7 permanently on, L2 a real gate

Captain Bob, 2026-11-12: "Wire L2, keep L7 on". The table held the 128
cards of the 7-bit L1-L7 space; nothing read L7, and the rolling window
recorded whatever the card said, so the 128 were 32 behaviours.

- compudynamics.c: cd_tuning_word() sizes the table to 64 (L1-L6).
- ssm_jacquard.c: card_bits() makes a card's 7-bit mask, L7 set, where a
  card is read, seeded and started (C4: 17 -> card 8);
  ssm_l8_force_config() still takes the 7-bit index, its L7 bit implied.
- physics_execution_hooks.c, kernel vm_core.c: the rolling window records
  only while L2 is on (or before there is a config).
- ssm_jacquard.h says what is wired, bit by bit (it said L7 was);
  v3/CLAUDE.md and the L8 reference corrected in place; FABRIC-3 XLVIII.21.

Tests first, seen to fail against HEAD (logs/20261112-210510/kernel-tests):
test_ssm_jacquard 4 of 7, test_physics_l2 1 of 4; all pass now. v4 reads
no rolling window: acceptance is unchanged; the protocol runs next.
