Update mcp gateway launch script to delete server config file

[Copilot]

Updates the MCP gateway launch script to delete the MCP server configuration file at /home/runner/.copilot/mcp-config.json after the gateway is successfully launched and configured.

Changes Made

Modified actions/setup/sh/start_mcp_gateway.sh to add cleanup logic that:

• Deletes /home/runner/.copilot/mcp-config.json after gateway setup is complete
• Runs after the gateway is started, converter scripts execute, and MCP server checks pass
• Works for all engine types (copilot, claude, codex, and fallback)
• Follows the same cleanup pattern as the existing gateway output file deletion

Implementation Details

The cleanup code (lines 416-424) safely checks if the file exists before deletion and provides informative status messages. This ensures the configuration file is only present while needed during gateway setup and is immediately cleaned up after use, improving security by not leaving configuration data on disk unnecessarily.

Testing

• ✅ Script syntax validated
• ✅ Code formatting passed (make fmt)
• ✅ Unit tests passed
• ✅ Changes follow existing codebase patterns

Pull request overview

Updates the MCP gateway startup script to delete the generated Copilot MCP config file (/home/runner/.copilot/mcp-config.json) after gateway startup completes, mirroring the existing cleanup of gateway-output.json.

Changes:

• Add post-start cleanup that removes /home/runner/.copilot/mcp-config.json if present.
• Emit status messages indicating whether the config file was deleted or not found.

[Copilot]

Deleting /home/runner/.copilot/mcp-config.json here will likely break later agent execution: the Copilot engine sets GH_AW_MCP_CONFIG to this path when MCP servers are enabled, and the runtime expects the file to exist during the actual Copilot CLI run. If cleanup is desired for security, consider moving it to the end of the job (e.g., in stop_mcp_gateway.sh or a dedicated always() cleanup step) or gating it behind an opt-in env flag so the config remains available for the agent.
