[gHashTag]

Closes #1737.

This PR adds the Wave Loop 766 witness and closeout artifacts.

What

• specs/scratch/w766_bench_module_351x2p6_aos_var_call_write.t27: 22,464 elements, 718,848-bit packed vector (~0.686 MiBit).
• scripts/gen_w766.py: generator for the witness.
• bootstrap/tests/icarus_lowerable.rs: integration test accepts_w766_bench_module_351x2p6_aos_var_call_write.
• Seal + empty Icarus baseline.
• Closeout report docs/reports/FPGA_LOOP_CLOSEOUT_W766_2026-07-23.md.
• W767 plan .claude/plans/wave-loop-767.md and updated .trinity/current-issue.md.

Not changed

• No compiler changes; FROZEN_HASH unchanged.
• No reference-model changes.

Verification

• cargo build --release -p t27c: OK
• cargo test -p t27c --bin t27c: 1494/0/2
• cargo test -p tri: 78/0
