perf: overlap sidebar-scope loads with worktree scan at startup (#7225) (#7306)
* perf: overlap sidebar-scope loads with worktree scan at startup (#7225)

Continues the renderer-chain parallelization proposed in #7225 (proposal 2),
on top of the merged #7266:

- Run project-groups → folder-workspaces concurrently with the per-repo
  `git worktree list` fan-out. Neither reads the repos store nor worktrees,
  so a slow remote host's 15s scope RPCs no longer queue ahead of the scan.
- Raise worktree refresh concurrency 5 → 8 so multi-core machines run fewer
  sequential scan batches, still bounded so one moment can't launch every
  git probe at once.

* Test overlapping sidebar scope loads and worktree hydration at startup

Verify that sidebar scope loads and worktree hydration operations run
concurrently before session hydration. This protects against regressions
in startup performance under the perf/startup-lag optimization.

Additionally, document the rationale for the worktree refresh
concurrency limit in the worktrees slice.

* Clarify worktree refresh concurrency comment
