Function qn_safe_segment

internal/cbm/extract_defs.c:3785–3818

Push a simple class definition (used by config language extractors). Replace each run of whitespace in `name` with a single '-' so the value is a well-formed QN segment. Markdown headings (e.g. "Codebase Memory") legitimately contain spaces; embedding them verbatim in a QN makes it malformed. Returns the original pointer when there is no whitespace to collapse. The human-readable def.name is kept

// original pointer when there is no whitespace to collapse. The human-readable
// def.name is kept intact; only the QN segment is slugified.
