The short version

What changed, and why it matters

This commit simply bumps the project's `bitcoin-lib` dependency from version 0.44 to 0.45 and updates the corresponding cryptographic library checksums. The commit message says the new version changes how the app binds to the secp256k1 library and adds support for a new Bitcoin output type called P2A. There is no code change in this repository itself, and no security fix or vulnerability is mentioned.

Recommended action

Review the bitcoin-lib 0.45 and secp256k1-kmp 0.21.0 release notes for any security-related fixes or breaking changes. Verify the published checksums match the updated values. Since this is a dependency-only change, no immediate code-level remediation is indicated, but standard dependency hygiene (audit, test, and monitor) applies.
