Pull request overview
This PR improves the ContractNotFound error message by appending a helpful hint when the provided “contract id” looks like a 32-byte Wasm hash (64 hex chars), addressing the UX gap described in #817.
Changes:
- Extend the
contract not founderror to optionally include a Wasm-hash-specific hint. - Add a small helper (
wasm_hash_hint) to detect 64-char hex strings. - Add unit tests covering hint/no-hint cases (plain alias, hex length checks, hex casing).
