craftkit v1.54.0

Codex-native agents and working-tree change scope

Codex ran CraftKit's agents by shelling out to codex exec, and every review and context
step compared only committed branch work, so unstaged and untracked edits went unreviewed.

• Named agents now install for Codex as TOML profiles under ${CODEX_HOME:-~/.codex}/agents/:
  read-only sandbox, medium reasoning effort, the configured model. Profiles CraftKit does
  not own are left alone.
• hooks/craftkit-codex.js loads a short Codex runtime guide, taken from a CRAFTKIT-CODEX
  block in using-agent-skills, in place of the Claude routing text.
• New partials/change-scope.md is injected into every review, ship, build, fix, context and
  eval workflow. Change scope now covers staged, unstaged and untracked files as well as the
  committed diff, and reports cannot-verify when no base resolves.
• scripts/test-codex.py covers the Codex hook and adapter.

Claude-side regressions found in review and fixed

• Platform detection treated any package.json as RN/web. Codex narrowed it to roots with a
  React dependency, which routed RN monorepos (React only in a workspace package) as plain
  Node and dropped fe-rules. Detection now also reads workspace packages from
  workspaces, lerna.json or pnpm-workspace.yaml.
• The Claude and Gemini adapters strip the CRAFTKIT-CODEX block, so Codex-only guidance
  no longer loads in every session there.
• Shared commands no longer hardcode this repo's bash check.sh as the verification command.
• The parallel classifier again tells Claude to launch every agent and the background test
  run in one message.
• check.sh 23b gains a monorepo fixture, a Node-without-React fixture, and an assertion that
  the Claude block carries no Codex section.
