Teknium 9442a718da fix(update-check): recover the real behind-count via the GitHub compare API
The honesty half (no fabricated counts) leaves shallow installs permanently
count-less. The compare API knows the full graph regardless of local clone
depth: GET /repos/<o>/<r>/compare/<current>...<target> returns ahead_by —
exactly the behind count the shallow boundary lost.

- hermes_cli/banner.py: _github_compare_behind() (bounded, unauthenticated,
  best-effort); wired into _check_via_rev and the shallow branch of
  _check_via_local_git. ahead_by==0 with differing tips = local-ahead => 0.
- hermes_cli/update_cmd.py: hermes update --check shallow path prints the
  exact count when recoverable, presence-only wording otherwise.
- apps/desktop/electron/update-count.ts: compareApiUrl() +
  parseCompareBehindCount() pure helpers; main.ts fetches the count when
  resolveBehindCount() returns null, and the SSH-official passive path stops
  fabricating behind:1 (uses compare API + updateAvailable flag).
- apps/desktop/src/lib/version-status.ts: updateAvailable now applies to the
  client target too, so a shallow desktop install shows '(update)' instead of
  nothing (or the old frozen '(+1)').

Fixes #84591; CLI siblings of #78253 / #53479 behavior.

E2E: live compare API returned 61/62 for real 61/62-commit gaps and 0 for the
reversed (local-ahead) pair; real shallow-clone fixture (depth-1 clone +
depth-1 fetch, merge-base broken) recovers the exact count with the API and
falls back to the honest sentinel offline.
