chore: bump ldk-node to rc.34 (stale monitor recovery + secrets reset)

Update from c5698d0 (pre-rc.33, no monitor overwrite protection) to
153ecbe (rc.34) which includes:
- accept_stale_channel_monitors flag
- BuildError.DangerousValue variant
- Commitment secrets reset on force_set_latest_update_id
- Delayed chain sync with keysend-based healing
- Sentinel skip in provide_secret for reset trees
