Add GitHub Actions for CI, releases, and Docker

CI workflow:
- Build and test on push/PR
- golangci-lint for code quality

Release workflow:
- GoReleaser for cross-platform binaries
- Triggered on version tags (v*)

Docker workflow:
- Build and push to ghcr.io
- Tagged with version and sha

Also:
- Added badges to README
- Added binary installation instructions
- Added Docker pull instructions
