When OpenClaw restarts under load, the Feishu bot-info probe
(`/open-apis/bot/v3/info`) can exceed the 10-second timeout due to
event-loop contention during channel initialization. This leaves
`botOpenId` empty, causing `checkBotMentioned()` to return `false`
for every group message — silently dropping them all while DMs
continue to work fine.
Two fixes:
1. **Increase startup probe timeout from 10s to 30s** and make it
configurable via `OPENCLAW_FEISHU_STARTUP_PROBE_TIMEOUT_MS` env var.
The previous 10s budget was too tight when multiple channels
(Slack, Discord, Feishu) initialize concurrently.
2. **Graceful degradation in `checkBotMentioned()`**: when `botOpenId`
is unknown, return `true` (assume mentioned) instead of `false`.
This prevents group messages from being silently discarded when the
probe fails for any reason. The trade-off is that the bot may
respond to non-@-mentioned messages temporarily until the next
successful probe, which is far preferable to total silence.
