Dylan Conway 50e478dcdc fix(crypto): correct method and constructor names mangled by number renamer (#26876) ...

## Problem

The bundler's number renamer was mangling `.name` properties on crypto
class prototype methods and constructors:

- `hash.update.name` → `"update2"` instead of `"update"`
- `verify.verify.name` → `"verify2"` instead of `"verify"`
- `cipher.update.name` → `"update3"` instead of `"update"`
- `crypto.Hash.name` → `"Hash2"` instead of `"Hash"`

### Root causes

1. **Named function expressions on prototypes** collided with other
bindings after scope flattening (e.g. `Verify.prototype.verify =
function verify(...)` collided with the imported `verify`)
2. **Block-scoped constructor declarations** (`Hash`, `Hmac`) got
renamed when the bundler hoisted them out of block scope
3. **Shared function declarations** in the Cipher/Decipher block all got
numeric suffixes (`update3`, `final2`, `setAutoPadding2`, etc.)

## Fix

- Use `Object.assign` with object literals for prototype methods —
object literal property keys correctly infer `.name` and aren't subject
to the renamer
- Remove unnecessary block scopes around `Hash` and `Hmac` constructors
so they stay at module level and don't get renamed
- Inline `Cipheriv` methods and copy references to `Decipheriv`

## Tests

Added comprehensive `.name` tests for all crypto classes: Hash, Hmac,
Sign, Verify, Cipheriv, Decipheriv, DiffieHellman, ECDH, plus factory
functions and constructor names.
