Kaspre 8399ff888f docs(system event): document --session-key timing exception
Codex review on PR #78687 [P3] flagged that the docs say next-heartbeat
"waits for the next scheduled tick" while the patched timer collapses
next-heartbeat+sessionKey to an immediate targeted wake. Add a callout
describing the exception and pointing callers who want delayed delivery
back at the no-session-key path.

Refs #78687.

# `openclaw system`
System-level helpers for the Gateway: enqueue system events, control heartbeats,
and view presence.
All `system` subcommands use Gateway RPC and accept the shared client flags:
- `--url <url>`
- `--token <token>`
- `--timeout <ms>`
- `--expect-final`
## Common commands
```bash
openclaw system event --text "Check for urgent follow-ups" --mode now
openclaw system event --text "Check for urgent follow-ups" --url ws://127.0.0.1:18789 --token "$OPENCLAW_GATEWAY_TOKEN"
openclaw system heartbeat enable
openclaw system heartbeat last
openclaw system presence
```
## `system event`
Enqueue a system event on the **main** session by default. The next heartbeat
will inject it as a `System:` line in the prompt. Use `--mode now` to trigger
the heartbeat immediately; `next-heartbeat` waits for the next scheduled tick.
Pass `--session-key` to target a specific session (for example to relay an
async-task completion back to the channel that started it).
> **Timing exception with `--session-key`:** when `--session-key` is supplied,
> `--mode next-heartbeat` collapses to an immediate targeted wake instead of
> waiting for the next scheduled tick. Targeted wakes use heartbeat intent
> `immediate` so they bypass the runner's not-due gate that would otherwise
> defer (and effectively drop) an `event`-intent wake. If you want delayed
> delivery, omit `--session-key` so the event lands on the main session and
> rides the next regular heartbeat.
Flags:
- `--text <text>`: required system event text.
- `--mode <mode>`: `now` or `next-heartbeat` (default).
- `--session-key <sessionKey>`: optional; target a specific agent session
instead of the agent's main session. Keys that do not belong to the
resolved agent fall back to the agent's main session.
- `--json`: machine-readable output.
- `--url`, `--token`, `--timeout`, `--expect-final`: shared Gateway RPC flags.
## `system heartbeat last|enable|disable`
Heartbeat controls:
- `last`: show the last heartbeat event.
- `enable`: turn heartbeats back on (use this if they were disabled).
- `disable`: pause heartbeats.
Flags:
- `--json`: machine-readable output.
- `--url`, `--token`, `--timeout`, `--expect-final`: shared Gateway RPC flags.
## `system presence`
List the current system presence entries the Gateway knows about (nodes,
instances, and similar status lines).
Flags:
- `--json`: machine-readable output.
- `--url`, `--token`, `--timeout`, `--expect-final`: shared Gateway RPC flags.
## Notes
- Requires a running Gateway reachable by your current config (local or remote).
- System events are ephemeral and not persisted across restarts.
