Refactor: Achieve Gemini CLI Parity & Remove Legacy Claude Artifacts (#46)

This pull request removes the deprecated Claude Flow command documentation and migration summary files, and updates Hive Mind session protocols to use Gemini Flow MCP tools instead of Claude Flow. The changes reflect a migration from the older Claude Flow agent and command system to the newer, more capable Gemini Flow platform.

Migration and documentation cleanup:

* Removed the entire migration summary document `.claude/agents/MIGRATION_SUMMARY.md`, which outlined the plan for moving from command-based Claude Flow to agent-based Gemini Flow.
* Deleted all coordination command documentation files in `.claude/commands/coordination/` including `README.md`, `swarm-init.md`, `agent-spawn.md`, and `task-orchestrate.md`, removing legacy usage instructions and examples.

Hive Mind protocol and tool migration:

* Updated Hive Mind session configuration files (`.hive-mind/sessions/hive-mind-prompt-swarm-1754080677307-azu23tze3.txt` and `.hive-mind/sessions/hive-mind-prompt-swarm-1754081983462-u8ohklimp.txt`) to replace all references to MCP tools prefixed with `claude-flow` with their `gemini-flow` equivalents, ensuring that collective intelligence, queen coordination, worker management, task orchestration, and memory/learning operations now use Gemini Flow tools.

* Updated Hive Mind initialization protocols in the same session files to use Gemini Flow agent spawning and memory storage commands, aligning batch tool operations with the new platform.
