Twelve format crates had no workflow of their own: xml, mime, cfb, mesh,
metafile, dxf, gcode, svg-paths, silhouette-studio, tiff, heif and cms
(cms ran only under the PDF workflow's paths). formats.yml runs fmt,
clippy (default, each feature alone, all features), the tests and a
wasm32 check for each.
The coverage build compiled none of the codec code that sits behind
features that are off by default, so new code in craft-video, craft-audio
and craft-media read as untested and failed the quality gate. The
SonarCloud job now passes those features to the shared workflow.
video.yml's per-feature clippy also covers vp9-decode and vp9-encode.
