Fredrik Johansson b47f659b7d feat: identity export/import (yaw-key-backup-1) ...

Portable encrypted identity backup compatible with the sister project's
format — argon2id KDF + nacl secretbox, peer ID visible in plaintext for
pre-import verification.

- crypto: ExportIdentity, ImportIdentity, SaveIdentity
- proto: export_identity / import_identity IPC commands + events
- ipc: export_identity returns encrypted blob; import_identity validates
  and decrypts (read-only — on-disk write requires daemon restart)
- netmgr: MasterIdentity() accessor
- daemon: --import-identity / --import-passphrase flags write identity.json
  and exit, enabling scripted account migration
- tests: roundtrip and wrong-passphrase rejection
