fix(ship-check): pass Codex attribution model

[aliasunder]

Summary

• pass the exact Codex model ID from the ship-check dispatcher to every committing phase agent
• keep Claude and OpenCode attribution tied to their runtime-exposed model identifiers
• preserve per-run model overrides without adding model pins to agent definitions or generated files
• carry the resolved attribution ID into inline pr-monitor runs

Verification

• plan-check: ready with 0 findings
• Codex sync generator: 17 tests passed
• disposable Codex sync: 6 agents generated; second check reported 0 changes
• generated-agent contract check passed across all four committing reviewers
• git diff --check passed
