Add manage_genie_instructions MCP tool for Genie space instructions

[CheeYuTan]

Summary

• New manage_genie_instructions MCP tool that exposes the existing core library instruction management capabilities
• Supports: list, add_text, add_sql, add_sql_function, add_batch actions
• The core library already had genie_list_instructions, genie_add_text_instruction, genie_add_sql_instruction, etc. but these were not accessible via MCP tools
• This enables LLM agents to programmatically configure Genie spaces with text guidance and SQL examples

Test proof

TEST 1 - List instructions: 6 found
  - [TEXT_INSTRUCTION] Notes
  - [SQL_INSTRUCTION] Current OEE vs Target by Line (latest completed ho
  - [SQL_INSTRUCTION] Find when L3 first dropped below 0.75 and consecut

TEST 2 - Instruction types found: {'TEXT_INSTRUCTION', 'SQL_INSTRUCTION'}
  PASS
