Pull request overview

This PR makes WearOS treat Bluetooth connections as a valid online state, so that when a watch is connected to a phone via Bluetooth (but has no WiFi or cellular), the app no longer shows the offline indicator. Previously, only WiFi and Cellular were considered valid connection types.

Changes:

• Added NetworkType.BT as a valid connected network type in ConnectivityStateManager
• Updated and added tests to verify Bluetooth is treated as connected and transitions work correctly
• Bumped version to 8.7-rc-1 / 9411 and updated release notes and CHANGELOG for the 8.7 release cycle

The CHANGELOG.md checklist item in the PR description is checked ("I have added an entry in CHANGELOG.md"), but the 8.8 section is empty. There should be an entry describing this change, e.g., under Bug Fixes or Updates, noting that Bluetooth connections are now counted as online state on WearOS.

I believe this PR was meant to target the release branch instead of main so I have changed it.
