BaseLanceNamespaceSparkCatalog passes lowercased option keys to LanceNamespace.connect()

[Yohahaha]

Description

CaseInsensitiveStringMap is Spark's wrapper that lowercases all config keys. In BaseLanceNamespaceSparkCatalog.initialize(), there are two places extracting options from it:

Line	Code	Result
225	new HashMap<>(options.asCaseSensitiveMap())	✅ Keys preserve original case
254	new HashMap<>(options)	❌ Keys are lowercased

Line 254 produces namespaceOptions with all-lowercase keys, which is then passed to LanceNamespace.connect() and eventually to the storage backend. Any backend that expects case-sensitive config keys will fail to find them.

Fix

One-line change at line 254:

- Map<String, String> namespaceOptions = new HashMap<>(options);
+ Map<String, String> namespaceOptions = new HashMap<>(options.asCaseSensitiveMap());

Other paths (LanceDataset, LanceDataSource) already correctly use asCaseSensitiveMap().
