Recreation of the #204 work from closed PR #205 (invalid provenance), rebuilt
cleanly on master under the prgs author identity with no PR #203 content:
- Add gitea_lock_issue MCP tool: locks exactly one issue to its branch name,
fails closed on branch/issue-number mismatch and on issues already tied to
an open PR (by head branch or Closes/Fixes reference).
- gitea_create_pr now requires the issue lock: head must match the locked
branch, title/body must contain Closes/Fixes #<locked issue> exactly, and
ambiguous references (equivalent / related / same as) are rejected.
- scripts/worktree-start refuses to create an issue-linked worktree unless the
lock file exists and matches the requested branch.
- assess_controller_handoff rejects handoffs whose selected issue / opened PR
fields carry multiple numbers or fuzzy equivalence wording.
- Tests: TestIssueLocking (lock + create_pr gates), handoff exact-reference
tests, worktree-start lock coverage.
Closes#204
