Continue the mechanical packed-vector array-of-struct ladder.

  • OUTER = 583, MID_IDX = 291
  • Elements = 583 × 2⁶ = 37,312
  • Packed vector = 37,312 × 32 = 1,193,984 bits ≈ 1.139 MiBit
  • Variant A from W881 cooperation plan: non-power-of-two outer-dimension [583][2]^6 Pt module-scope variable from call with indexed signed writes.
  • Zero compiler / reference-model / FROZEN_HASH changes expected for witness.

Acceptance criteria:

  • Generator scripts/gen_w882.py with copy hazard fixed before first run.
  • Spec specs/scratch/w882_bench_module_583x2p6_aos_var_call_write.t27 parses.
  • t27c icarus-lowerable, icarus-simulate, icarus-cocotb, and seal --save PASS.
  • Integration test added to bootstrap/tests/icarus_lowerable.rs.
  • Full cargo test --release --test icarus_lowerable passes at 342/0.
  • bootstrap/stage0/FROZEN_HASH unchanged.
  • Closeout report + W883 cooperation plan + tracker updates.
  • Commit with Closes #{issue}, push branch, open PR.

…wo outer-dimension array-of-struct variable from call with indexed signed writes (Closes #1812)

- OUTER = 583, MID_IDX = 291
- Elements = 583 × 2⁶ = 37,312
- Packed vector = 37,312 × 32 = 1,193,984 bits ≈ 1.139 MiBit
- Continues the non-power-of-two outer-dimension array-of-struct packed-vector ladder.
- Zero compiler / reference-model / FROZEN_HASH changes for witness.
- Generator copy-hazard prevented by pre-run grep of all three stale-reference locations.

Validation matrix:
- t27c parse → PASS
- t27c icarus-lowerable → lowerable
- t27c icarus-simulate → PASSED (17 cycles)
- t27c icarus-cocotb → reference-model OK
- t27c seal --save → seal saved
- cargo test --release --test icarus_lowerable accepts_w882_bench_module_583x2p6_aos_var_call_write → passed
- Full suite → 342/0
