Fix C++ MIDI-CI Profile Parsing in PROFILE_INQUIRY_REPLY

Fixes the issue where PROFILE_INQUIRY_REPLY messages created empty profile vectors instead of parsing the actual profile data from the sysex message, implementing the C++ equivalent of Kotlin's CIRetrieval.midiCIGetProfileSet() functionality.

Problem

The C++ implementation in Messenger::process_input() was creating empty std::vector<std::vector<uint8_t>> for both enabled and disabled profiles when processing PROFILE_INQUIRY_REPLY messages, instead of parsing the actual profile data from the sysex bytes. This prevented proper profile inspection message processing.

Solution

Changes Made:

• Modified PROFILE_INQUIRY_REPLY case in Messenger::process_input() to extract profile data from bytes 13+ of the sysex message
• Reused existing ProfileReply::deserialize() method for proper parsing of enabled and disabled profiles
• Added size check to ensure minimum data length before parsing
• Fixed PROPERTY_SUBSCRIPTION_REPLY to properly extract body data from the message

Implementation Details:

• Extracts profile data starting from byte 13 (after the common MIDI-CI header)
• Uses the existing ProfileReply::deserialize() method which correctly implements the parsing logic that matches the Kotlin reference
• The deserialize method properly handles:
  • Reading number of enabled profiles from first byte (with 7-bit masking)
  • Extracting 5-byte profile IDs for each enabled profile
  • Reading number of disabled profiles after enabled ones
  • Extracting 5-byte profile IDs for each disabled profile

Testing

• ✅ Build passes without compilation errors
• ✅ All profile-related tests pass (8/8 tests)
• ✅ General MIDI-CI tests pass
• ✅ Parsing logic matches Kotlin CIRetrieval.midiCIGetProfileSet() implementation

Verification

The fix ensures that profile data is properly extracted and parsed from MIDI-CI messages, enabling correct profile inspection and further profile-related message processing that was previously broken due to empty profile vectors.
