/**
 * Handle a hivemind-session-view tool call.
 *
 * GAP-01 fix (sidecar-completeness-2026-06-06): the previous implementation
 * called `st.get(sessionId)` but DISCARDED the result, always returning
 * `{ ok: true, data: { sessionId } }` with no real data. This fix:
 *   - Uses the typed `registry.sessionTracker` getter (no `(registry as any)`)
 *   - Captures the `sessionTracker.get()` result and returns the full record
 *   - Throws `[Hivemind]` if `sessionTracker` is not bound (registry design
 *     contract — typed getter throws on unbound access)
 *   - Returns a NOT_FOUND error envelope if the session is not found
 *
 * @param options.args - Query args (sessionId).
 * @param options.registry - Sidecar dependency registry.
 * @returns Unified session view, or an error envelope.
