Function dashboard_sources_changed

build.rs:198–206

True when the dashboard source inputs differ from the content stamp recorded by the previous build in this `OUT_DIR` - i.e. the sources genuinely changed rather than just having their mtimes rewritten by a `git checkout`/`pull`. A build with no recorded stamp (a fresh checkout, a clean target dir, or a crates.io build that ships only dist) returns false here; the dist-carried source stamp is chec

/// crates.io build that ships only dist) returns false here; the dist-carried
/// source stamp is checked separately before this OUT_DIR fallback is used.

/// True when the committed/generated dist was built from a different set of
