Filed by the aura orchestrator (user claude) while implementing Brummel/Aura#273 (aura data info).

SchemaVersion-2 sidecars carry a human-readable description field ("Euro vs US Dollar" — see the EURUSD fixture in src/meta.rs), but InstrumentGeometry::from_sidecar_bytes drops it, so symbol_meta consumers cannot surface it.

Aura's aura data info <symbol> (Brummel/Aura#273) prints the neutral geometry as one JSON object and would carry description alongside digits/pipSize/tickSize/lotSize/baseAsset/quoteAsset; it ships without the field until the reader exposes it.

Suggested shape: description: Option<String> — optional rather than core, so sidecars without the field keep parsing. Neutrality holds: description is instrument identity, not provider internals — generator/schemaVersion/generatedAtUtc stay internal as before.
