description	Run clang-tidy on C++ files changed relative to main and report violations

clang-tidy

Run clang-tidy on every C++ file that differs from main and report violations with file:line context.

Steps:

1. Check that .vscode/build/compile_commands.json exists. If not, tell the user to run cmake -B .vscode/build first and stop.

2. Find changed C++ files:

   git diff --name-only main...HEAD -- '*.cpp' '*.h' '*.hpp'
   

   Also include any untracked files in src/, lib/, or include/ that are not in .pio/, build/, or _deps/.

   If no C++ files are changed, report "No C++ files changed relative to main." and stop.

3. For each file, run:

   clang-tidy -p .vscode/build <file>
   

4. Collect all output. Report:

   • A summary line per file: OK or the number of warnings/errors
   • Full violation details (file:line:col: warning/error: message [check-name]) for any file with findings
   • An overall count: N files checked, M violations found

If clang-tidy is not installed, report the error and stop. Do not auto-fix — report only.
