feat(cli): tri igla — search/list/gate/check/triplet for IGLA RACE ledger

[gHashTag]

Summary

Adds a tri igla subcommand family — five commands for querying the IGLA RACE training ledger (trios-trainer-igla/assertions/seed_results.jsonl) and the embargo list.

Command	Purpose
tri igla search	Filter by --seed, --bpb-max, --step-min, --sha, --gate-status. Emits canonical R7 triplet per match.
tri igla list --last N	Last N rows in triplet form (default 10).
tri igla gate --target T	Gate-2 quorum check: PASS iff ≥3 seeds satisfy bpb < T AND step ≥ 4000. Exit 0 on PASS, 2 on NOT YET.
tri igla check <sha>	Embargo refusal (R9). Exits non-zero if SHA is on assertions/embargo.txt.
tri igla triplet <i>	Print canonical R7 triplet for row index i.

Constitutional discipline

• CANON_DE_ZIGFICATION: spec authored first at specs/cli/igla.t27 (10 test, 6 invariant, 3 bench, ASCII-only). Backend at cli/tri/src/igla.rs mirrors the spec 1:1.
• NO-COMMIT-WITHOUT-ISSUE: tracked under feat(cli): tri igla — search/list/gate/check/triplet commands for IGLA RACE ledger #541.
• NO-MUTATION-WITHOUT-SKILL: PHI LOOP recorded under .trinity/state/, .trinity/seals/CliIgla.json, .trinity/events/akashic-log.jsonl.

Hashes

• spec_hash_after = cf443c08…3063f
• gen_hash_after = 3d5ed0ea…46698
• test_vector_hash = 6a6256e8…17a15a

Tests

• cargo test (in cli/tri/): 17/17 pass — all spec tests, invariants, format-bpb edge cases.
• E2E smoke against synthetic 4-row ledger + 8-SHA embargo:
  • gate --target 1.85 → PASS quorum=3/3 (rc=0)
  • check 477e3377 (embargoed) → REFUSED (rc=1)
  • check 2446855 (clean) → OK (rc=0)
  • search --bpb-max 1.85 --step-min 4000 → 3 hits
  • triplet 0 → BPB=2.497 @ step=12000 seed=43 sha=6a40e17 jsonl_row=1 gate_status=below_target_evidence
• cargo fmt --check clean.

Closes #541
