#109 feat: add codecov and REUSE compliance

- Add codecov.yml with coverage targets (95% project, 90% patch)
- Add REUSE compliance structure (.reuse/dep5, LICENSES/)
- Add SPDX headers to all Rust files (MIT license)
- Switch from dual license to MIT only
- Add test analytics via cargo-nextest with JUnit XML output
- Add coverage job using cargo-llvm-cov
- Add codecov upload for both test results and coverage
- Add REUSE lint step to CI workflow
