refactor: simplify publish pipeline and collapse duplicated stage errors
Follow-up cleanup on the publish-failures change.

Error model:
- Collapse `Error::{Engine, Publish, Handler}` into one `Error::Stage` with an
  `ErrorStage` discriminator. The three shared a field shape and had to be
  edited together in four match groups; nine near-identical constructors
  become two private helpers.
- Add `Error::failure_reason()`, replacing the same error -> FailureReason
  mapping written out in four places.
- Publish errors are now terminal. Publish runs once, after execution, so no
  caller could ever act on the retryable classification.

Publish phase:
- Fix: a branch that was pushed is now still reported when pull request
  creation fails afterwards. `PublishOutcome` records what happened and
  carries the error separately, instead of hiding both behind a `Result`.
- Drop `PublishOutcome::NoChanges`, which no consumer distinguished from
  `Published { pr_url: None }`.
- Move publish onto `Concluded` as methods and replace three near-identical
  precondition guards with one `publish_target()`.

Pull requests:
- `maybe_open_pull_request` -> `open_pull_request` returning the record
  directly. Both callers already reject empty diffs, so the `Ok(None)` path
  was unreachable.
- Drop `CreatedPullRequest.head_sha`, which echoed back its own input.

GitHub client:
- Delete `branch_exists`, which had no callers and duplicated
  `branch_head_sha`. Give `branch_head_sha` the `_with_client` split every
  sibling has and port the tests to `MockHttpClient`.
- Collapse the copy-pasted credential match in `resolve_clone_credentials`.

Events:
- `PullRequestCreated.head_sha` is `Option<String>` instead of using an empty
  string to mean absent.
- Centralize the run-branch refspec in `lifecycle::git::push_run_branch`, so
  `git.push` reports a branch name from both emitters as documented.

refactor: deduplicate cached-run access and event scans
- Add AppState::cached_run with the standard 500/404 mapping and use it
  everywhere handlers read the shared run-projection cache. This also
  normalizes two inconsistencies: graph-source cache errors now map to
  500 (was 502), and a missing projection in PR create/unlink now maps
  to the canonical 404 (was a bespoke 500).
- Extract an EventScan cursor shared by the four run-event scan loops,
  delegate list_events_from to the paginated variant, and stop the
  stage-event scan once its page is full instead of walking the rest of
  the log.
- Hold Arc<RunProjection> in the local projection cache so opening a run
  no longer deep-copies the projection (copy-on-write via Arc::make_mut),
  and drop the now-unreachable shared-cache branch in last_event_seq.
- Trim hot-path clones: run_files serves the projection Arc directly,
  run-state serializes by reference, artifacts only checks existence, and
  the command-log handler opens a reader only for the CAS-blob branch.
