thePR0M3TH3ANandClaude Sonnet 5 283840261f Add NIP-04 support for drop-in NIP-07 parity ...

signEvent() already handles any event kind and NIP-44 was already
implemented, but window.nostr.nip04 (and the equivalent element-scoped
nip04Encrypt/nip04Decrypt) didn't exist anywhere -- every real NIP-07
extension exposes it, and sites with legacy DM code paths still expect
it. A site whose own code called window.nostr.nip04.encrypt(...) while
BitLogin was the active signer got a bare "Cannot read properties of
undefined" instead of a working call.

- packages/core/src/crypto/nip04.ts: AES-256-CBC + secp256k1 ECDH
  shared secret (raw X coordinate, no HKDF -- this is legacy NIP-04,
  not NIP-44), "<ciphertext>?iv=<iv>" payload shape, cross-checked
  against the NIP-04 spec's algorithm description
- NostrSigner.nip04Encrypt/nip04Decrypt, mirroring the existing
  nip44Encrypt/nip44Decrypt methods
- crypto worker: new nip04Encrypt/nip04Decrypt actions and protocol
  payload types
- <bitlogin-auth>.nip04Encrypt/nip04Decrypt (element-scoped, like the
  existing nip44 methods) and window.nostr.nip04.encrypt/decrypt
