fix: use neutral service names to avoid OpenClaw gateway detection

OpenClaw's gateway scans LaunchAgent plists and systemd units for
"openclaw" markers and flags them as conflicting gateway-like services.
Renamed service identifiers to avoid false positives:

- macOS: ai.openclaw.proxy → dev.ocp.proxy
- Linux: openclaw-proxy.service → ocp-proxy.service
- Logs: ~/.openclaw/logs/ → ~/.ocp/logs/

Setup auto-removes legacy service names on upgrade. Uninstall handles
both old and new names. Also bumps version to 3.1.0.
