The queen agent currently jumps straight into building without a planning phase, and its prompt documents only coder-tools file I/O names (read_file, write_file, etc.) without mentioning the worker's hive-tools equivalents (view_file, write_to_file, etc.). This causes the queen to mistakenly instruct workers to use tools they don't have.

Changes:

• Add a planning phase with read-only tools and dedicated knowledge prompt for collaborative goal-setting before building
• Add a "Worker File Tools" section documenting hive-tools MCP names so the queen references correct tool names for workers
• Add replan_agent lifecycle tool to return from building to planning
• Update frontend to display phase state
• Improve debug script for queen prompt inspection
