Adopt an already-published PR instead of publishing again
Fixes counterexample 5 from specs/orchestrator.qnt. A crash after the
PR was opened but before PR_OPEN was recorded left the agent in
EXECUTING; the restart question's 'continue' and 'start' then published
again, Gitea refused a second PR, and there was no way back to PR_OPEN.
On the live run the executor model happened to notice the existing
work; recovery must not depend on that.

- Boot (A3 step 4): in EXECUTING, if Gitea shows the milestone's PR
  open, adopt it, watch it from the start, and resume in PR_OPEN with a
  notice. Gitea unreachable or the PR closed: the restart question, as
  before.
- MilestonePublisher.publish is idempotent: after pushing, an open PR
  for the branch is adopted (and so updated) rather than a second one
  opened. This also covers a PR opened whose response was lost.
- The model adopts too, gains the lost-response outcome, and now counts
  PRs opened per milestone (one_pr_per_milestone was a flag the fixed
  model could never set). A mutant without adoption fails the new
  scenario; the properties held over 200,000 traces each.

nisse-dev

The Dev Agent: plans and implements software projects, produces Gitea PRs for human review, and reacts to review comments and commits. A thin application over the shared nisse-core library.

Part B of the specification at ../docs/Architecture-Build-Spec.md covers this agent; Part A covers the library it sits on.
