## [Unreleased]

### Added
- **Version Catalog**: Centralized dependency management via `gradle/libs.versions.toml`.
- **Dependabot**: Automated weekly dependency update checks for Gradle and Cargo.
- **CI Release Automation**: Automated GitHub Actions job building Windows (`hermes-pair-windows-x86_64.exe`) and Linux (`hermes-pair-linux-x86_64`) binaries on tag push (`v*`) with automated `SHA256SUMS.txt` generation.
- **Repository Documentation**: Added `SECURITY.md`, `CONTRIBUTING.md`, `CHANGELOG.md`, and `LICENSE` tracking.
- **Gradle Optimizations**: Parallel execution, build caching, 4GB JVM heap, and non-final resource IDs in `gradle.properties`.

### Changed
- **Binary Hygiene**: Removed tracked binary distribution files (`hermes-pair/dist/**`) from git repository tracking; updated `.gitignore` and `README.md` to instruct downloading from GitHub Releases or building from source.
