fix: skip migration on unreadable existing monitor instead of failing (rc.36)

When orphaned channel migration encounters an existing monitor that can't
be deserialized (e.g. UnknownVersion), skip the migration instead of
killing node startup with ReadFailed. The existing data is preserved.

Also adds HTLC timeout force-close fix to CHANGELOG (from rc.35).

 ## Bug Fixes
 
+- Fixed orphaned channel migration blocking node startup when the existing monitor
+  in the KV store can't be deserialized (e.g., `UnknownVersion` from a newer LDK
+  version). The migration now skips writing and lets the node start normally,
+  preserving the existing monitor data.
+- Fixed HTLC timeout force-close during stale monitor recovery. The healing keysend
+  created HTLCs with a stale `cltv_expiry` (based on the ChannelManager's outdated
+  best block height for users offline >24h). When chain sync caught up, LDK
+  force-closed the channel (HTLCsTimedOut). Fix: sync the chain tip before sending
+  healing payments so HTLCs get a valid CLTV expiry. If sync fails, skip the keysend
+  to avoid the stale-CLTV force-close.
 - Fixed native crash (SIGABRT) during stale channel monitor recovery. The
   `CounterpartyCommitmentSecrets` store was not reset when force-syncing the
   monitor's `update_id`, causing `provide_secret()` to fail validation after
