- keep only the options that differ from Google style, each annotated with
the Google default, so every override carries its own rationale
- switch to Allman braces and a 120 column limit; short functions now
collapse only when declared inline
- dropped overrides fall back to Google behaviour, which turns include
sorting, argument binpacking, comment reflow and namespace comment
fixing back on
- drop a stray trailing blank line in .clangd
