Drop redundant runOnUiThread in getCurrentPosition handler

[timbortnik]

LocationProvider.getCurrentPosition already invokes its callback on the main thread — requestLocationUpdates is registered with the main Looper, the timeout uses a main-Looper Handler, and the early-return paths run synchronously on the calling (main) thread. Wrapping result.success in runOnUiThread was therefore unnecessary indirection.

Per CodeRabbit review on #18.
