v1.4.1

What's Changed

• Renamed analyze_schema → discover_schema across the entire codebase to prevent LLMs from confusing "analyze my data" with schema discovery
• discover_schema returns early when workspace is already restored — no redundant re-discovery
• get_table_details uses cached data from session and discourages bulk usage
• sample_table_data auto-fills schema_name from session when omitted
• execute_sql_query recommends semantic layer (OBML) when available
• Updated all integration examples, docs, skills, and tests
