craftkit v1.51.0

Codex loads CraftKit rules and checks verification at Stop

Codex previously installed full rules as files but loaded only a short guide into the
session. Skill and workflow routing depended on the agent choosing to read and follow them.

• adapters/codex.sh registers a native Codex gateway in ~/.codex/hooks.json while
  preserving other hooks. Codex requires a /hooks review and trust before it runs.
• SessionStart loads the full applicable rule bodies, including platform-scoped rules only
  where their platform matches. UserPromptSubmit supplies routing guidance and the
  installed body of an explicitly requested $skill or leading /command.
• Stop compares the working tree with its turn-start snapshot and continues a turn that
  edited files but skipped the project's verification command. It preserves the baseline
  across its automatic continuation and limits blocks to two. Pre-existing dirty files do
  not trigger the gate.
• check.sh exercises rule scoping, explicit command loading, pre-existing edits,
  verification continuations, and idempotent hook registration. A live Codex smoke test
  confirmed that skipping verification after an edit triggers the Stop continuation.

The runtime does not expose native skill activation as a stable hook event, so following a
skill's instructions remains an agent responsibility; the verification command is the
mechanically enforced part.
