Add MSP2_INAV_LOGIC_CONDITIONS_CONFIGURED command
11ca236 
Returns 8-byte bitmask indicating which logic conditions differ from defaults.
Enables configurator optimization to reduce MSP requests from 64 to 1+N.

Fix cppcheck critical bugs: integer overflow and buffer overrun
111894c 
Two bugs found by cppcheck static analysis:

1. fc/config.h:66 - Integer overflow in FEATURE_FW_AUTOTRIM
   - `1 << 31` could cause signed integer overflow (undefined behavior in C)
   - Fixed by using `1U << 31` for unsigned shift

2. sensors/temperature.c:101 - Buffer overrun in memset
   - sizeof(array) is already the size in bytes, so should not be multiplied by element size.
   - Fixed by using just `sizeof(sensorStatus)`

Fix CRSF buffer overflow and dashboard sizeof bug
cdca77e 
CRSF buffer overflow (rx/crsf.c):
- fullFrameLength computed from untrusted frameLength field
- Malformed packet with large frameLength could overflow crsfFrame.bytes[]
- Added bounds check against CRSF_FRAME_SIZE_MAX before writing

Dashboard sizeof bug (io/dashboard.c):
- tickerCharacters was a pointer, so sizeof() returned pointer size (4/8)
- On 64-bit systems, TICKER_CHARACTER_COUNT was 8 instead of 4
- Could read past end of string when indexing tickerCharacters[]
- Changed to array declaration and sizeof()-1 for correct count

Branch Targeting Suggestion

You've targeted the master branch with this PR. Please consider if a version branch might be more appropriate:

  • maintenance-9.x - If your change is backward-compatible and won't create compatibility issues between INAV firmware and Configurator 9.x versions. This will allow your PR to be included in the next 9.x release.

  • maintenance-10.x - If your change introduces compatibility requirements between firmware and configurator that would break 9.x compatibility. This is for PRs which will be included in INAV 10.x

If master is the correct target for this change, no action is needed.

This is an automated suggestion to help route contributions to the appropriate branch.
