fix(bfld): make README quickstart test robust to CRLF line endings

readme_quickstart_uses_canonical_public_api checked a multi-line needle
'pipeline\n    .process' against the include_str! README. On a CRLF
checkout (Windows / core.autocrlf) the content is 'pipeline\r\n    .process',
so the LF needle never matched and the test failed deterministically (only
surfaced once the worldmodel fix let cargo test --workspace run on Windows;
the test is #[cfg(feature=std)]-gated, enabled via workspace feature
unification). Normalize CRLF->LF before the check. Full workspace now green
3/3 runs on Windows.
