feat: PQ NIF, sustainability flag, autoremove, proven fix, integration tests

- Add PQ NIF module (Opsm.Crypto.PostQuantum.Nif) with Rust native
  crate implementing Dilithium5, Kyber-1024, SPHINCS+ via pqcrypto
- Add --sustainability/-s CLI flag, wired through install handlers
- Implement real autoremove command with orphan dependency detection
  using installed.json and lockfile dependency graph
- Fix proven dependency: SafeColor guard ordering, SafeCurrency abs/1
  conflict, SafeJson get_in/2 conflict, SafeFloat infinity check,
  SafePhone default args, add Jason as optional dep
- Replace regex-based Mix.exs parsing with AST-based extraction of
  project fields, deps, and licenses
- Add 49 integration tests for SLSA, PQ trust, and manifest pipelines
- Bump mix.exs version to 2.0.0, add castore dep
- 547 tests + 40 properties passing (8 pre-existing PQ NIF failures)
