Function cbm_lsp_bare_segment

src/pipeline/lsp_resolve.h:49–65

Bare last segment of a (possibly qualified) name, splitting on the LAST * member/scope separator. C++ textual callees carry `::` (Class::method, * Ns::f) and `->` (p->run), while the LSP records dotted internal QNs * (Class.method). Splitting only on '.' (strrchr) leaves `Math::square` * and `p->run` intact, so they never match the LSP's `square`/`run` short * name and the type-aware strategy

 * languages' callee names contain none of `::`/`->`, so this is a no-op
 * for them. */
