chore(fleet): erp#63 evidence — verifier parity + builder bench transcripts

- runs/2026-07-18/: the 8 sha256-pinned verifier transcripts (4 runtimes ×
  2 tests), blind-judging verdicts (2 independent judges per cell, unanimous),
  the erp#56 builder-bench journal + prompt + caps, and the evidence README
  with the parity table.
- run-verifier.sh: mistral runtime drops the tool-filter flag (--enabled-tools
  with a no-match pattern hangs vibe 2.21.0); plain -p with --max-turns 1.

Verdicts: Mistral (vibe -p, mistral-medium-3.5) and Ornith 35B (hermes MLX)
reach verdict parity with the Claude baseline on both tests → admitted to
verifier duty. Qwen2.5-7B-4bit fails both → the honest small-model floor.
Builder bench: erp#56 completed by the Mistral runtime, 0 code corrections,
261 s, acceptance run clean (0 bank-UNKNOWN) → merged as PR #68.

Closes #63 (with the paired factory qa-strategy PR).
