fix(mesh): sync terminal status codes and implement periodic ghost mirror cleanup

fix(orchestration): resolve skill hallucination, brace crashes, and silent turns in swarm control ...

- Implemented strictly-worded 'Tool-belt' in system prompt to prevent hallucinating external skills.
- Replaced fragile .format() with robust .replace() for system prompts to prevent crashes on curly braces.
- Optimized TTS streaming: increased concurrency and reduced chunk sizes to eliminate mid-sentence pauses.
- Fixed 'silent turn' bug in Swarm Control by ensuring fallback content is yielded even if AI only produces reasoning/tools.
- Improved history formatting to handle assistant turns mapping to tool calls without main content.
- Corrected Gemini model fallback to gemini-1.5-flash.

feat: enhance swarm terminal UI and AI command execution ...

- Implement resizable terminal height in Swarm Control page
- Improve AI command execution with better status tracking and output streaming

fix: Solve node thread saturation by serializing PTY session access and fixing cancellation leaks

fix: Solve silent node capacity rejections and improve SubAgent retry logic

feat: Remove DSPy dependency and implement Swarm Control ...

- Removed DSPy-based pipelines (code assistant, file selector, question decider).
- Implemented Swarm Control for multi-node command execution and terminal handling.
- Updated gRPC services for batch command processing and improved perception.
- Replaced Coding Assistant page with Swarm Control interface in the UI.
- Updated Protobuf definitions to support interactive terminal sessions.
- Improved node registry and RAG services for better agent performance.
