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.
