This fixes two issues that caused BLE connections to hang on macOS
when not using the --debug flag:
1. Race condition in BLEClient event loop initialization
- The event loop thread was started but asyncio operations were
submitted before the loop was actually running
- Added threading.Event synchronization to ensure the event loop
is running before any operations are submitted
- The ready signal is sent from within the loop via call_soon()
to guarantee the loop is truly active
2. CoreBluetooth callback delivery on macOS
- On macOS, CoreBluetooth requires occasional I/O operations for
callbacks to be properly delivered to the main thread
- Without --debug, no I/O was happening, causing callbacks to
never be processed and operations to hang indefinitely
- Added sys.stdout.flush() call before waiting for async results
to trigger the necessary I/O
The --debug flag masked these issues because:
- Debug logging introduces timing delays that let the event loop start
- Logger I/O triggers the necessary callback delivery mechanism

Ensures that automatic replies are sent back on the same channel index the message was received on. Previously, all replies defaulted to the primary channel (0), even if the incoming message arrived on a secondary channel. Additionally it ensures incoming messages match the specified channel index.
E.g: meshtastic --ch-index 1 --reply .
Modified the `onReceive` handler to extract the `channel` index from received packets. This ensures `interface.sendText` targets the originating channel rather than always defaulting to the primary channel. Added a filter to ensure that only the specified channel index is being replied to.
this function, xor_hash, and a variable for the default key (as bytes, I think, rather than the base64 version) really all belong in meshtastic.util rather than here.
There's multiple forms of hashing in firmware so this should be named to denote that, perhaps channel_hash. If we later want to add the frequency-slot-style hash, better if it's distinguished better from the start.
