Align Flow lib defs for Node.js crypto with v24

Summary:
This is an AI-assisted change to align the Flow definitions for the `crypto` module with the Node.js docs as at v24.

**New v24 APIs:**

1. **`hash(algorithm, data, [outputEncoding])`** - One-shot hashing convenience function
   - Added in Node.js v21.7.0, v20.12.0
   - https://nodejs.org/api/crypto.html#cryptohashalgorithm-data-outputencoding

2. **X509Certificate new properties** (added in v22.10.0):
   - `validFromDate` - Certificate valid-from as Date object
   - `validToDate` - Certificate valid-to as Date object
   - https://nodejs.org/api/crypto.html#x509certificatevalidfromdate
   - https://nodejs.org/api/crypto.html#x509certificatevalidtodate

**New Classes:**

3. **KeyObject** - Represents cryptographic keys (symmetric/asymmetric)
   - Properties: `type`, `asymmetricKeyType`, `asymmetricKeySize`, `symmetricKeySize`
   - Methods: `export()`, `equals()`
   - https://nodejs.org/api/crypto.html#class-keyobject

4. **X509Certificate** - X.509 certificate handling
   - Properties: `ca`, `fingerprint*`, `issuer`, `subject`, `publicKey`, `raw`, etc.
   - Methods: `checkEmail()`, `checkHost()`, `checkIP()`, `verify()`, etc.
   - https://nodejs.org/api/crypto.html#class-x509certificate

5. **Certificate** - Legacy SPKAC (Signed Public Key and Challenge) support
   - Static methods: `exportChallenge()`, `exportPublicKey()`, `verifySpkac()`
   - https://nodejs.org/api/crypto.html#class-certificate

**Key Management Functions:**

6. **Key Creation:**
   - `createSecretKey(key, [encoding])` - Create symmetric KeyObject
   - `createPublicKey(key)` - Create public KeyObject
   - `createPrivateKey(key)` - Create private KeyObject
   - https://nodejs.org/api/crypto.html#cryptocreatesecretkeykey-encoding
   - https://nodejs.org/api/crypto.html#cryptocreatepublickeykey
   - https://nodejs.org/api/crypto.html#cryptocreateprivatekeykey

7. **Key Generation:**
   - `generateKeyPair()` / `generateKeyPairSync()` - Generate asymmetric key pairs
   - `generateKey()` / `generateKeySync()` - Generate symmetric keys
   - Supports: RSA, RSA-PSS, DSA, EC, Ed25519, Ed448, X25519, X448
   - https://nodejs.org/api/crypto.html#cryptogeneratekeypairtype-options-callback
   - https://nodejs.org/api/crypto.html#cryptogeneratekeytype-options-callback

8. **Primality Testing:**
   - `checkPrime()` / `checkPrimeSync()` - Test if candidate is prime
   - https://nodejs.org/api/crypto.html#cryptocheckprimecandidate-options-callback

**Other Improvements:**

9. **Hash.copy()** - Create deep copy of Hash object
   - https://nodejs.org/api/crypto.html#hashcopyoptions

10. **webcrypto property** - References web Crypto type
    - Web Crypto API types are NOT redefined (use existing definitions where available)
    - https://nodejs.org/api/webcrypto.html

**Type Safety:**
- All options objects use modern `Readonly<{...}>` syntax for inputs
- Exact-by-default types throughout
- Proper overloading for functions with optional parameters

**References:**
- Node.js crypto module docs: https://nodejs.org/api/crypto.html
- Node.js Web Crypto API: https://nodejs.org/api/webcrypto.html
