Altium PcbLib — native footprint parser

Native Rust crate that parses Altium .PcbLib (and .IntLib) binary footprint libraries — OLE2 Compound File container with Altium's reverse-engineered binary record format inside. Emits KiCad-shaped pad JSON so chipsmith, concur, and any other Adom tool that needs to read Altium binary footprints pulls from one source of truth instead of re-implementing OLE2 walking + binary record decoding. Public Rust API: parse_altium_pcblib_path(&Path), parse_altium_pcblib_bytes(&[u8]), render_footprint_svg(&Value), render_all_footprints_svg(&Value). Bundled CLI: altium-pcblib-svg <path> [--all] [-o out.svg] — emits the authoritative parser-side SVG so a downstream renderer disagreeing with the SVG is provably the bug, not the parser. Source is private (github.com/adom-inc/altium-pcblib); depend via Cargo path in the same workspace, or git URL on a build container.
