feat(corpus,security): expand Isabelle corpus to 105 entries and resolve security alerts

- Removed binary artifact: src/chapel/proof_search
- Updated dependencies: rand, rustls-webpki
- Expanded ProverKind to 105 variants and updated Idris2 injectivity proof
- Merged unique Isabelle synthetic proofs from PR #27
