Named paths let you navigate by structure name instead of opaque indices.
Both formats work in all MCP tools:
- Index: "(0 3 2)"
- Named: "defisland > let > letrec"
The server detects ">" in the path string and calls resolve-named-path
(SX function) which walks the tree matching child names at each level.
New SX functions: resolve-named-path, split-path-string, find-child-by-name.
MCP server: added trim/split primitives, resolve_path dispatcher.
