OptionChainAnalytics 3.0.0

Breaking CBOE terminology release. Replaces the legacy local-data API with DataSource.CBOE_LOCAL, load_local_cboe_options_data, map_cboe_options_data, and the [cboe] optional dependency. Normalized local caches now use option_chain_analytics.cboe.normalized metadata and must be rebuilt. Python support remains >=3.10. See CHANGELOG.md for full migration details.
