- Modified the CI workflow to copy the `libsecp256k1.so` file to the root directory for test accessibility.
- Enhanced the `InitPub` method in the `FallbackSigner` to parse the x-only public key for verification.
- Bumped version to v0.25.6 to reflect these updates.
- Enhanced the Signer struct to include a FallbackSigner for scenarios where the libsecp256k1 implementation is unavailable.
- Updated the New function to initialize the fallback signer when the context creation fails.
- Refactored methods in the Signer to delegate operations to the FallbackSigner when applicable, ensuring compatibility with pure Go implementations.
- Added comprehensive method implementations for the FallbackSigner, including key generation, signing, and verification.
- Improved error handling and memory management in the new implementation.
- Added `github.com/ebitengine/purego` as a direct dependency to the project.
- Removed the unused `p8k.mleku.dev` dependency from the `go.mod` file.
- Refactored the `GenerateConversationKeyFromHex` function to clarify parameter order, aligning with the NIP-44 specification.
- Enhanced test cases for conversation key generation to ensure proper handling of public key formats and improved error messages.
- Updated the `Signer` interface to include methods for extracting and serializing public keys in compressed format.
- Added a pong handler to extend the read deadline upon receiving PONG messages in WebSocket connections, improving connection stability.
- Updated the signer implementation to serialize the x-only public key to 32 bytes, ensuring compatibility with the internal format.
- Refactored tests to utilize MustNew() for signer initialization, enhancing error handling during key generation.
- Bumped version to v0.25.1 to reflect these updates.
- Replaced all instances of p256k1signer with the new p8k.Signer across various modules, including event creation, policy handling, and database interactions.
- Updated related test cases and benchmarks to ensure compatibility with the new signer interface.
- Bumped version to v0.25.0 to reflect these significant changes and improvements in cryptographic operations.
