v0.8.0

Added

• Background service — claumon service install registers claumon to start automatically on login. Works cross-platform: LaunchAgent on macOS, systemd user unit on Linux, scheduled task on Windows. No root required.
• Self-update — claumon update checks GitHub releases, downloads the correct binary for your platform, replaces the current one, and restarts the service if installed.
• Version subcommand — claumon version prints the version and exits.

Platform handling

• macOS — automatically clears quarantine/provenance attributes and re-signs the binary after download or service restart, preventing Gatekeeper from blocking execution.
• Windows — strips Mark of the Web (Zone.Identifier) on downloaded binaries to avoid SmartScreen blocks.
• Linux — README documents loginctl enable-linger for keeping the service running after logout.
