- Worktree-flow section now describes resolveBranchForJob (sibling
reuse), feat/story-<id> naming, deferred cleanup while siblings are
active, and the 1-PR-per-story result.
- File table corrects the heartbeat description (PR #14 made it
self-healing instead of self-terminating).
Closes the docs task in story 'Voorkom doublure-PRs' under PBI 'Veilige
Claude-agent-workflow'.
