FlowSight Agent 5.0.7 — browser setup and local tools

FlowSight 5.0.7 adds a guided browser setup in Settings: open the official Chrome Web Store listing, copy the local pairing key, and verify the Arc/Chrome connection. The key is masked in the app and browser actions remain optional and confirmation-gated. The local automations and Coach UI are included in this Windows release. Chrome Web Store review is still pending, so the store may not allow new installs until Google publishes the listing. Calendar companion remains dependent on Cloud backend deployment credentials and should not be treated as live until those are configured. The signed Windows installer and updater manifest are attached automatically by the release workflow after its build completes.
