Summary

Brings the chore--profiling branch into development. Combines profiling/benchmark work, official PASETO test-vector support, a Rust core restructure, and updated docs/steering.

Changes

  • Rust core restructure: split the monolithic lib.rs into focused modules (bindings.rs, paseto.rs, token.rs, token_generator.rs, exceptions.rs, etc.).
  • Test vectors: add official PASETO v2/v3/v4 test vectors plus Rust loader and property-based test suites.
  • Test structure: move Python tests under tests/python/; add tests/rust/ suites and tests/vectors/ JSON.
  • Docs: add README with performance benchmarks and comparison table; refactor .kiro/steering guides.
  • Build: update Cargo.toml and pyproject.toml.

Testing

  • cargo test / cargo test --features test-vectors
  • pytest (after maturin develop)
