The short version

What changed, and why it matters

This commit updates Eclair to use a newer version of its underlying Bitcoin library (bitcoin-lib 0.46). The main change is a code refactor in how Taproot addresses and scripts are created: instead of passing an optional script tree, callers now explicitly choose between a 'key path' tweak (for simple key-spending) or a 'script path' tweak (for script-spending). The commit also updates related cryptographic checksums and test code. There is no direct evidence in the commit message or diff that this fixes a known security vulnerability; it appears to be a routine dependency and API refactor.

Recommended action

Treat as a normal dependency/API refactor. Review the bitcoin-lib 0.46 release notes or changelog for any security-related fixes, but based solely on this commit there is no actionable security issue. Ensure the checksums match the published artifacts and run the updated test suite.
