**Profile deletion with undo functionality** (2026-08-22):
- Users can delete a profile via `nostr-manager-backend delete-profile <npub>`, which moves the profile to an in-memory undo stack rather than permanently removing it
- Profiles can be restored with `nostr-manager-backend undo-delete`, which pops the last deleted profile from the undo stack and re-adds it to the vault (becoming active if no other profile exists)
- The undo stack is in-memory only (lost on process exit); a persistent implementation would require vault metadata changes
- Vault must be unlocked or unencrypted for deletion to be permitted
- Existing profile data and vault integrity are preserved
- CLI commands: `delete-profile <npub>` and `undo-delete`
- Rust changes verified: `cargo test` (91 tests), `cargo clippy --all-targets` clean, `cargo fmt --check` clean, `cargo build --release` successful
Possible future work (not audit items): DNS-rebinding TOCTOU in the SSRF guard, OS keyring integration for the vault password, an automated dependency-audit CI job (`cargo audit`, `npm audit`), GUI integration for profile deletion/undo in the ProfilesScreen.
