craftkit v1.50.0

Cold agents skip CLAUDE.md

Every agent spawn loaded every CLAUDE.md layer: the ~45 KB CRAFTKIT managed block, the
project CLAUDE.md and its imports. None of it was needed, since the rules an agent works
by already arrive through craftkitInject. A bulk-read probe that made no tool calls cost
32.6k tokens, and a third of that was the global block alone.

• All 16 agents/*.md set omitClaudeMd: true (Claude Code v2.1.271+). The same probe
  now costs 6.6k, and fe-review 9.4k. Org managed policy still reaches both agents, which
  the go/no-go probe checked alongside the absence of three phrases found only in the managed block.
• The field drops the project CLAUDE.md too, which a second probe confirmed. The
  CONTEXT: payload in parallel-review, parallel-ship and parallel-build now carries a
  PROJECT CONVENTIONS: entry: the root CLAUDE.md, its @-imports, and the
  .claude/rules/*.md files without paths:, or not present when there are none. Agents
  spawned outside those three (plan-roaster, eval-judge, bulk-read) judge plans, scores or
  one named file, so they go without it. CLAUDE.local.md, nested CLAUDE.md files and
  path-scoped rules are not carried either, which is a known gap.
• check.sh check 39 fails an agent without the field and a template without the entry.
• Authoring rule #4 in the repo CLAUDE.md and the README agents notes say so.
• To roll back, delete the field. Nothing on disk changes shape.

Stop gate stops blaming a turn for files dirty before it

When a turn wrote through the shell or spawned an agent, the verification gate added every
dirty file in the working tree to that turn's edits. So one untracked planning doc, last
touched the day before, blocked every turn that delegated work.

• gitDirty counts only files modified since the prompt that opened the turn (startedAt,
  now read from the transcript by craftkit-transcript.js). It compares max(mtime, ctime),
  because a chmod moves only ctime. A deleted file, or a turn with no start time, still counts,
  so the gate errs on the side of firing.
• git status --porcelain -z replaces the line-based parse. A rename now resolves to its new
  name instead of old -> new, and a name with a space is no longer quoted.
• check.sh check 23 gains fixtures for a stale delegating turn, a fresh one, a git mv,
  a quoted name and a chmod-only change. The last three failed before the fix.
