Renn F a9fc870415 fix(orchestrator): harden external-PR supersede close-on-land
Scope close_pull_request repo resolution by project_id and thread the
umbrella's project into close-on-land, so a contributor PR is never
resolved (or closed) against a same-numbered PR in another project's
repo. Skip the comment + close PATCH when the PR is already closed, so a
retried sweep never re-posts the 'superseded' comment.

Require a non-cancelled descendant that actually landed a PR before
retiring the contributor PR, so an umbrella force-completed over a
cancelled code subtask leaves the contributor's still-valid PR open.

Run close-on-land from the always-on sweeper rather than the default-off
poll loop, so a supersede that lands after the feature is toggled off is
still reconciled. Serialize concurrent supersede triggers under a lock so
a double-click can't cut two branches / spawn two umbrellas. Anchor the
supersede marker checks to the marker line so appended CEO notes can't be
mistaken for the closed/dedup tokens. Make the fork-head branch cut
idempotent (forced refspec) so a commit-fail retry converges.

Also drop an importlib.reload(roboco.config) in a unit test that rebound
the settings singleton and leaked into the PM decision-window test.

"""GitService PR-divergence primitives: rebase_onto_base + close_pull_request.
These back both the sequence-ordered merge (rebase a later sibling onto the
prior one's merged result) and the conflict resolver (rebase a wedged PR,
then close-if-superseded / re-merge / escalate). The classification a rebase
yields — superseded vs rebased vs conflicts — drives the whole resolution, so
each branch is pinned here against a mocked git.
