q2r (development version)

• First development version. Wraps the pampa Rust crate from quarto-dev/q2 to expose Quarto’s QMD parser to R.
• parse_qmd() returns either a Pandoc AST (pandoc) or a tree-sitter AST (ts_tree), with structured parse diagnostics attached.
• to_qmd() renders an R-held AST back to QMD (Pandoc via pampa’s writer, tree-sitter via byte recovery).
• A tidyselect-style query/rewrite vocabulary works across both ASTs: select_nodes(), select_descendants(), select_children(), select_first(), walk_nodes(), map_nodes(), replace_nodes(), delete_nodes(), splice_nodes(), insert_before(), insert_after().
• Document-level helpers (ast_summary(), ast_sections(), select_section(), ast_toc(), split_sections()), code-cell helpers (cell_options(), set_cell_options(), collect_code()), table bridges (as_df(), as_table()), file I/O (read_qmd(), write_qmd(), edit_qmd()), multi-document collections (parse_qmd_dir()), and a tree-sitter query escape hatch (ts_query()).
