Add native security key registration, reference import, and signing on macOS and iOS. Store references in Vault metadata and route authentication through connection, Assistant, MCP, and agent forwarding flows.
Preserve signing cancellation and actionable authentication errors for security keys and Secure Enclave. Pin the released libssh2 forks as nested submodules and refresh package resolution.
Share Vault, persistence, SSH/SFTP, forwarding, and SwiftUI components across platforms. Add mobile editors, terminal input, standalone Assistant, Metrics navigation, transfers, and a unified Live Activity with host system icons.
Validation: 35 iOS tests and 100 focused macOS tests pass; formatting and zh-Hans checks pass. The full macOS run reports 14 issues in the documented timing, Keychain, and popover suites. Remaining Assistant tool and CloudKit work is tracked in Memory/MOBILE_ROLLOUT.md.
