This PR introduces the foundational cryptographic key management system for Sovereign Identity in Timmy.

What's New

  • src/timmy/identity module with KeyVault class
  • Ed25519 key generation for Nostr identities
  • AES-256-GCM encryption at rest (passphrase-derived via PBKDF2)
  • Operations: create, load, list, delete, rotate passphrase
  • Comprehensive pytest suite (7 tests)

Design

  • Local-first: keys never leave the machine
  • Encrypted: each identity stored as encrypted JSON at ~/.timmy/identity/<name>.json
  • Minimal surface: clear API, easy to audit
  • Ed25519 first: Nostr-compatible; extensible to Bitcoin/secp256k1

Dependencies

  • cryptography >= 46.0.0 (already in stack)

Closes #469

- Create src/timmy/identity module with KeyVault class
- Implement Ed25519 key generation for Nostr identity
- Encrypted at-rest storage using AES-256-GCM + PBKDF2
- Support: store, load, list, delete, passphrase rotation
- Add comprehensive pytest suite (7 tests, all passing)

This is the foundational cryptographic key management layer for
Sovereign Identity: local-first, passphrase-protected, ready for
Nostr (nsec) and future Bitcoin/secp256k1 support.

Closes #469
