JinjingandOrca 772081577e Fix fork PR/MR worktree creation race via durable review-head refs (#10429)
* Fix fork PR/MR worktree creation race via durable review-head refs

When creating a fork PR/MR worktree, concurrent `git fetch origin` operations
clobber the shared FETCH_HEAD, causing the wrong commit to be checked out.
Fetch PR/MR heads into dedicated per-review refs (`refs/orca/pull/<N>`,
`refs/orca/merge-requests/<N>`) that persist and isolate each head from other
fetches. Gracefully keep the compare-base when the fetch fails but the local
ref already exists, avoiding silent fallback to the wrong branch on transient
network errors.

* Bound PR/MR head fetches with 60s timeout

Prevent PR/MR creation from hanging when a remote is stalled or
unreachable. Both GitHub and GitLab head fetches now enforce a
60-second timeout, matching the bound used in the create-path
fetch. Durable refs (refs/orca/pull/*, refs/orca/merge-requests/*)
decouple the ref from FETCH_HEAD, preserving legacy client semantics.

* test: align CI expectations with main PowerShell/sparse regressions

PR checks merge into main, which recently changed PowerShell launch args
(cwd restore after profiles) and sparse-checkout detection (require
core.sparseCheckout). Derive PowerShell spawn args from the production
resolver, mock the sparse config flag, reset shared worktree list scan
cache between tests, and stop requiring floating polls to avoid getRepos
hydration.

* Address review follow-ups on durable review-head refs

- Unify PR review-head remote selection: local and SSH GitHub paths share
  resolveGitHubReviewHeadRemote, which prefers the remote mapping to the
  hosting GitHub project (upstream before origin, matching work-item/API
  candidate order) so contributor clones fetch refs/pull from the repo
  that actually hosts the PR.
- Soft-keep durable review heads: when the PR/MR head fetch fails but
  refs/orca/pull/<N> / refs/orca/merge-requests/<iid> still resolves,
  keep the pinned SHA (warn) instead of failing resolve, mirroring the
  compare-base fallback. Extracted shared compare-base soft-keep into
  compare-base-ref-fetch.ts.
- Extract fetchGitLabMergeRequestHeadRef (local + SSH) parallel to the
  GitHub helper; bound its local fetch with the shared 60s timeout.
- Share relay-style fetch validation (positive safe-integer id, remote
  not starting with "-") between relay and local helpers via
  review-head-tracking-ref.ts; move REVIEW_HEAD_FETCH_TIMEOUT_MS there.
- Drop the githubPullRequestHeadLocalRef re-export; resolve head SHAs via
  rev-parse --verify <ref>^{commit}.
- Add GitLab anti-FETCH_HEAD regression test plus durable-head soft-keep
  and remote-selection unit tests.

* test: supply live getRepos for terminal-retirement hydrates

Main's headless tab hydrate (#9343) skips worktree keys whose repo is not
in getRepos. Retirement tests that rebuild mobile tabs from a persisted
session now advertise the fixture repo as live so PR Checks merge stays green.

* fix(editor): extract RichMarkdownEditor props to stay under max-lines

Main's SSH external-image wiring (#10323) pushed RichMarkdownEditor.tsx over
the 400-line tsx budget, failing PR Checks lint on every merge into main.
Move the props type into a sibling module so the component stays under the
limit without disabling max-lines.

* Make durable review-head refs remote-identity scoped

Embed remote name + URL hash into refs/orca/pull|merge-requests refs to prevent soft-keep from serving wrong project's PR/MR when FETCH_HEAD is clobbered by concurrent fetch. Fetch functions now return the written ref path (writer-authoritative) so callers rev-parse exactly what was fetched, not re-derive identity. Soft-keep only applies to transient errors (timeout, network); fails hard on missing refs, auth failures, and stale relay. Relay returns localRef so client avoids re-hashing (URL normalization can disagree).
