Release v1.0.0 - Major security upgrade with Argon2id encryption

- Upgrade vault encryption from PBKDF2 (1000 iterations) to Argon2id
  (256MB memory, 8 iterations, 4 threads, ~3 second derivation)
- Add automatic migration from v1 to v2 vault format on unlock
- Add WebAssembly CSP support for hash-wasm Argon2id implementation
- Add NIP-42 relay authentication support for auth-required relays
- Add profile edit feature with pencil icon on identity page
- Add direct NIP-05 validation (removes NDK dependency for validation)
- Add deriving modal with progress timer during key derivation
- Add client tag "plebeian-signer" to profile events
- Fix modal colors (dark theme for visibility)
- Fix NIP-05 badge styling to include check/error indicator
- Add release zip packages for Chrome and Firefox
