ElementsProject/lightning v26.04.1 on GitHub

What's Changed

This is a hotfix release addressing build and protocol correctness issues found shortly after v26.04.

Gossip: Malformed channel_announcement messages where node_id_1 is not lexicographically less than node_id_2 are now rejected per BOLT spec (lightning/bolts#1333), preventing gossip store corruption and stress on readers. ([#9082])
Build: Fixed printf format specifiers for splice weight logging (%zu for size_t) across lightningd, channeld, and the spender plugin, resolving -Werror/-Wformat failures in Docker and 32-bit ARM cross-compilation. ([#9083], [#9086])
Build: Removed __int128 usage from bookkeeper currency rate math, restoring builds on 32-bit targets (armv7). ([#9085])
