feat(channels): expose channelExists through the bindings
Bumps vendor to pick up channelExists, cherry-picked onto the nim-ffi
0.2.0 lineage: the chore/channel-exists branch forked before that
migration, so its pre-0.2.0 {.ffi.} shape would not compile here.

The typed model carries a real bool, so channel_exists_async returns
Result<bool, _> rather than the "true"/"false" string the original
would have produced.
