Fixed two grammatical errors:

1. Changed "handle" to "handles" in the system architecture section
   - Original: "It runs Lua, as well as handle Bluetooth networking..."
   - Fixed: "It runs Lua, as well as handles Bluetooth networking..."
   - Explanation: The subject "It" (referring to nRF52) requires the third-person 
     singular verb form "handles" to maintain subject-verb agreement.

2. Changed "many" to "may" in the debugging section
   - Original: "You many need to unlock the device..."
   - Fixed: "You may need to unlock the device..."
   - Explanation: "Many" is a determiner/adjective meaning "a large number of", 
     while "may" is a modal verb expressing possibility. The context requires 
     the modal verb to indicate that unlocking might be necessary.
