Upgrade all core cryptographic dependencies to their latest versions:

Dependencies:
- digest: 0.10 to 0.11
- elliptic-curve: 0.13 to 0.14
- hkdf: 0.12 to 0.13
- hmac: 0.12 to 0.13
- rand: 0.8 to 0.10
- rand_chacha: 0.3 to 0.10
- sha2: 0.10 to 0.11
- getrandom: 0.2 to 0.4 (WASM)
- ml-kem: 0.3.0-rc.0 to 0.3
- ecdsa: 0.16 to 0.17.0-rc.23
- rfc6979: 0.4 to 0.6 (now internal to ecdsa)
- p256/p384/p521: 0.13 to 0.14.0-rc.15
- curve25519-dalek: 4 to 5.0.0-rc
- ed25519-dalek: 2 to 3.0.0-rc
- cryptoki: 0.9 to 0.12
- rustyline: 17 to 18
- scrypt: 0.11 to 0.12
- voprf replaced by voprf-vx 1.0.0-pre.0

Migration changes:
- generic-array 0.14 to 1.4 with hybrid-array 0.4 interop
- ArrayLength<u8> to ArrayLength (generic-array 1.x)
- Added ConcatExt trait to disambiguate from [T]::concat
- Replaced Hmac with SimpleHmac for digest 0.11 compatibility
- Added OutputSize<H>: ArrayLength bounds throughout Hash trait
- Converted hybrid_array::Array between GenericArray at API boundaries
- Updated GroupEncoding Repr bound to hybrid_array::Array
- ECDSA sign now uses ecdsa::hazmat::sign_prehashed_rfc6979
- Removed direct rfc6979 dependency (handled by ecdsa internally)
- Replaced bincode with postcard for no_std serialization
- Re-exported hybrid_array from crate root

Other changes:
- Renamed crate to opaque-vx
- Increased MSRV to 1.89
- Added cryptography to Cargo.toml categories
- Removed Facebook-specific contributions from CONTRIBUTING.md
- Removed v3 to v4 migration test
- Removed unstable rustfmt configurations for stable compatibility

daxpeddaandGitHub bebd2c605b SIGMA-I Key Exchange (#378)
* Move `KeGroup` to `KeyExchange::Group`

- Introduce `KeyExchange::Hash`, which separates the OPRF hash from the one used in `KeyExchange`.
- Remove `De/Serialize` requirement on key exchange messages and states, which forced a lot of where bounds on downstream users.
- Rename `KeGroup` to `Group`.
- Replace `D` generic for hash with `H`.

* Use `voprf::derive_key()` directly

* Implement SIGMA-I key exchange

* Improve `KeyExchange` for SIGMA-I and Ed25519

* Implement EdDSA

* Un-qualify some method calls

* SIGMA-I: only include client identity in client mac

* SIGMA-I: include server mac in client signature

* Expose key exchange types in `crate` & move modules

* Implement Ed25519ph

* Document `ed25519` crate feature

* Remove `ristretto255-voprf` crate feature

* Adjust CI crate feature testing

* Fix Rustdoc

* Remove unnecessary generic parameters from SIGMA-I

* Properly mark to-do's with TODO

* Assorted fixes

* SIGMA-I: include context in signature

* SIGMA-I: include identifiers in signature

* Merge `ServerLoginStart/FinishParameters`

* Re-export more necessary types

* More carefully expose types

* Add ECDSA test

* SIGMA-I: share context hashing

* De-duplicate client static public key storage

* Hide `KeyExchange` better

* Use the correct hash in the root documentation

* Bump `derive-where`

* Format documentation examples a bit further

* Add remote OPRF seed documentation

* Rename `deserialize_key_pair` to `deserialize_take_key_pair`

* Add more key tests

* Remove `SharedSecret` trait

* SIGMA-I refactor message API

* Share more implementation between 3DH and SIGMA-I

* Remove unnecessary zero scalar check for Curve25519

* Use correct hash in test

* Add some more TODOs

* Exclude `tests` folder from Cargo publishing

* Enable missing dependencies

* Use right crate for testing Ed25519

* Remove unnecessary `Sized` constraints

* Remove unnecessary `ecdsa` crate features

* Move signature de/serialization to trait methods
