scheduled prompts: add/remove targets on edit (#474 fast-follow)

@@ -14,7 +14,7 @@ Tools (hyperhive surface):
 - `mcp__hyperhive__request_schedule_prompt(targets, body, first_fire_at_unix, interval_seconds?, description?)` — queue an approval for the operator to add a scheduled prompt. On approve hive-c0re inserts a schedule row and the worker fans `body` out to each agent in `targets` at `first_fire_at_unix` (recurring every `interval_seconds` if set, one-shot when absent). Even self-targeted schedules go through approval — the existing `remind` tool stays the quick no-approval self-wake path. Catch-up clamp: long downtime fires ONCE per recurring row on resume (skipped count surfaces in per-target `last_result`), not N stacked pulses.
 - `mcp__hyperhive__cancel_schedule(id, targets?)` — cancel a schedule. Omit `targets` / pass empty to cancel the whole schedule; pass a list to cancel just those recipients (the schedule keeps firing for any remaining active targets, auto-cancels when every target is gone). Authorization: you can cancel schedules you own OR any owned by a sub-agent in your subtree per topology.json.
 - `mcp__hyperhive__fire_schedule_now(id)` — fire a scheduled prompt out of band. Runs the per-target fan-out once immediately. Recurring schedules keep their cadence intact (the manual fire is additive); one-shot schedules are CONSUMED by the manual fire (cancelled afterwards). Same authorization as `cancel_schedule`.
-- `mcp__hyperhive__edit_schedule(id, body?, description?, interval_seconds?, next_fire_at_unix?)` — partial-update a schedule's mutable fields (#474). Pass only the fields you want to change. Targets stay immutable (cancel + new schedule is the workaround). Refuses cancelled rows. Same authorization as `cancel_schedule`. Note: clearing fields (e.g. flipping recurring→one-shot) is operator-only via the dashboard PATCH — the agent surface only supports positive sets.
+- `mcp__hyperhive__edit_schedule(id, body?, description?, interval_seconds?, next_fire_at_unix?, targets_add?, targets_remove?)` — partial-update a schedule's mutable fields (#474). Pass only the fields you want to change. `targets_add` / `targets_remove` mutate the recipient list in the same transaction; re-adding a previously-cancelled target drops the tombstone + history (operator intent: "fresh start"). Refuses cancelled rows. Same authorization as `cancel_schedule`. Note: clearing scalar fields (e.g. flipping recurring→one-shot) is operator-only via the dashboard PATCH — the agent surface only supports positive sets on `description` / `interval_seconds`.
 - `mcp__hyperhive__list_schedules()` — snapshot every schedule in the queue (active + cancelled-but-not-reaped). Returns id, owner, body, target set with per-target `last_fired_at` + `last_result`, `next_fire_at_unix`, recurring `interval_seconds`. Use to look up an id before cancelling, or to audit upcoming wake-ups across the swarm.
 - `mcp__hyperhive__get_logs(agent, lines?)` — fetch recent journal lines for a sub-agent container. Use to diagnose MCP-server registration failures, startup crashes, or harness issues you can't see from inside. Pass the plain logical agent name; `lines` defaults to 50 (capped at 500).
 - `mcp__hyperhive__ask(question, options?, multi?, ttl_seconds?, to?)` — surface a structured question to the operator (default, or `to: "operator"`) OR a sub-agent (`to: "<agent-name>"`). Returns immediately with a question id; the answer arrives later as a system `question_answered { id, question, answer, answerer }` event in your inbox. Options are advisory: the dashboard always lets the operator type a free-text answer in addition. Set `multi: true` to render options as checkboxes (operator can pick multiple); the answer comes back as `, `-separated. Set `ttl_seconds` to auto-cancel after a deadline (capped at 6h server-side) — on expiry the answer is `[expired]` and `answerer` is `"ttl-watchdog"`. Do not poll inside the same turn — finish the current work and react when the event lands.
