Subject: [PATCH] feat(hermes-v12): Curator feature module on Mac + iOS (Phase
 D)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Hermes v0.12 ships an autonomous Curator that prunes / consolidates
agent-created skills on a 7-day cycle. This phase brings that surface
into Scarf so users can see status, trigger runs, pin protected skills,
and restore archived ones.

Pipeline:

- HermesCuratorStatus + HermesCuratorSkillRow: Sendable value types for
  parsed status + per-skill leaderboard rows.
- HermesCuratorStatusParser: pure text parser for `hermes curator status`
  stdout (no `--json` flag exists upstream). Tolerates Hermes's
  whitespace-padded leaderboard layout (`activity=  0` with N spaces
  between `=` and the value) by slicing between known key positions
  rather than splitting on whitespace. State-file JSON overrides
  text-parsed values for last_run_at / last_run_summary /
  last_report_path because the file carries full ISO timestamps the
  text output may have rounded.
- CuratorViewModel: @Observable @MainActor, drives the CLI verbs
  (status / run / pause / resume / pin / unpin / restore) via
  transport.runProcess so it works equally over local and Citadel SSH.
- HermesPathSet: adds curatorLogsDir + curatorStateFile (the latter
  is `.curator_state` with no extension despite holding JSON).

Mac:

- Features/Curator/Views/CuratorView.swift — page-header + status card
  + skill counts + pinned chips + 3 leaderboard tables (least recent,
  most active, least active) with inline pin toggles and a
  per-skill counter chip row. "Run Now" button + a kebab menu for
  Pause/Resume + Restore Archived.
- Features/Curator/Views/CuratorRestoreSheet.swift — name-entry sheet
  for `hermes curator restore <skill>`. Free-form text field; Hermes
  doesn't ship a `curator list-archived` yet so we don't synthesize a
  picker.
- Sidebar: AppCoordinator + SidebarView gain a `.curator` case under
  Interact (between Memory and Skills); the row is filtered out by
  SidebarView's capability-aware `sections` computed property when
  `HermesCapabilities.hasCurator` is false. ContentView routes
  `.curator` to CuratorView. Pre-v0.12 hosts see the v0.11 sidebar
  unchanged.

iOS:

- Scarf iOS/Curator/CuratorView.swift — read-mostly List with the same
  status / skill counts / pinned / leaderboards + inline pin toggles.
  Run Now / Pause / Resume actions in the section footer.
- ScarfGoTabRoot's System tab gains a Curator NavigationLink under
  Features, gated on `hasCurator`. Uses a stable
  `systemTabContextID` so the SSH transport pool reuses the cached
  Citadel connection keyed by that id.

Tests: 6 new parser tests (215 total, all green). Locks the empty-state
output captured from a real v0.12.0 install + paused-state + state-file
override + multi-word-name-row parsing. Both Mac and iOS schemes build
clean.
