feat(search): draw real node box from disabled-pack source

Click a node name (or 'Draw this node') in the mirror-search palette to render
an imitation ComfyUI node box with its real input sockets, widget defaults, and
output sockets. Since disabled packs aren't loaded (no /object_info entry), a
new read-only backend module (node_introspect.py) AST-parses the pack on disk —
never importing or executing it — to recover INPUT_TYPES / RETURN_TYPES from a
literal NODE_CLASS_MAPPINGS. New GET /nodes-stats/node-schema endpoint resolves
the disabled pack dir (handling @version suffixes / case) and returns the schema
off the event loop. Frontend lazily fetches + caches per node, renders sockets
vs widgets with type-colored dots, and falls back to a placeholder for packs
that build their node list dynamically.

End-to-end against the live install: 67/68 disabled packs resolve on disk, ~92%
of nodes render a real box, the rest fall back cleanly. Adds 7 parser unit
tests (36 total green). Bump to 1.6.0.
