Function resolve_rd_inline 

pub fn resolve_rd_inline(content: &str) -> SyntaxNode

Non-markdown twin of resolve_md_inline: lex content as a plain Rd prose fragment (no markdown recognizers; \name{…} macros still carve, gated by the backslash-pairing parity) and return the ROXYGEN_PARAGRAPH node. Drives the projector’s re-parse of a demoted markdown span’s rendered body, which tools::parse_Rd reads as ordinary Rd text once the generating macro’s backslash has been paired away.
