## Description
- Refactored `RLNWitnessInput` and `RLNProofValues` into struct/enum
(`SingleV1` / `MultiV1`) to cleanly support both standard and
multi-message-id modes.
- Added version byte retrieval methods for `RLNProof` and
`RLNWitnessInput`.
- Enhanced `ProtocolError` with new variants: `EmptyMessageIds`,
`DuplicateMessageIds`, `MissingSelectorUsed`, `NoActiveSelectorUsed`,
and `FieldLengthMismatch`.
- Read `MAX_OUT` value directly from the graph file instead of
hardcoding.
- Added checks for `message_ids`, `selector_used`, `path_elements`,
`identity_path_index` in proof gen api.
- Extended FFI (C/Nim/Rust) and WASM bindings with multi-message-id
support.
- Added multi-message-id CLI example and updated existing examples.
- Added multi-message-id circuit resources (`max_out_4`) for tree depth
10 and 20; removed tree depth 16 and 24.
- Updated CI with clippy checks and nightly release for the
`multi-message-id` feature flag.
- Version bump for dependencies in all modules.
- Exposed compute_id_secret as a public API and updated README on how to
use the slashing cross feature.
## Testing
- Added multi-message-id test cases for FFI, protocol, and public API.
- Added compatibility tests to verify new witness/proof types against
old serialized data.
