Audit fixes: log privacy, dead code, stale docs- The connect and Fast Pair probe log lines do not name the buds. A user can give the buds a personal name.- Core: the unused C interface (ffi.rs) and the cdylib crate type are gone.- Desktop: gdkwayland-sys is gone. On Linux only an AppImage updates itself; other builds open the release page.- Worker: the check for the removed Dev tools crash test is gone. The stats comment names /reports.- CI: SHA256SUMS needs a good Android job, except for an AppImage-only run.- Docs: 46 confirmed models in CONTRIBUTING, 29 feature-sync scenarios, no Find phone capture request, the tiles item states the current rule owner, MODELS.md names no phone model.
