/**
 * Fleet-health flag dispatcher — consume side of the platform fleet-health signal.
 *
 * A fleet-managed mount is bound live by the host fleet rclone, so it is excluded
 * from the boot-time no-phantom-workspace barrier. The in-container manager runs a
 * local `stat`/`readdir` probe that catches directly-detectable failures (EIO /
 * dead bind), but a *silently-empty-but-writable* degraded fleet mount is only
 * visible to the host, which knows `core/stats.errors`.
 *
 * The platform fleet-health poll writes its verdict for connector `<id>` into
 * `<workspace>/.skaile/fleet-health/<id>` (body: `healthy` | `degraded` |
 * `error`). The runner watches that directory and forwards each verdict to the
 * ConnectorManager's `reportFleetHealth`, which trips/lifts the read-only gate
 * with hysteresis.
 *
 * Contract:
 *   - dir:  `<workspace>/.skaile/fleet-health/`
 *   - file: one per connectorId; basename === connectorId.
 *   - body: trimmed, lowercased; `healthy` → healthy, `degraded` → degraded
 *           (live + readable but writes failing ⇒ read-only-readable surface),
 *           anything else (`error` | unreadable | empty) → error (fail-closed).
 *
 * Extracted so the watcher logic can be unit-tested without the WebSocket server.
