Support Vscode editor

[ericdallo]

Vscode support is ongoing on eca-vscode, but it is still not usable.

• Create the plugin/extension repo (editor-code-assistant/eca- would be ideal), ask maintainers for permission.
• Server
  • Manage ECA server process.
    • Automatic download of latest server.
    • Allow user specify server path/args.
    • Commands for Start/stop server from editor.
    • Show server status (modeline, bottom of editor, etc).
  • JSONRPC communication with eca server process via stdin/stdout sending/receiving requests and notifications, check protocol.
  • Allow check eca server process stderr for debugging/logs.
  • Support initialize and initialized methods.
  • Support exit and shutdown methods.
• Chat
  • Oepn chat window
  • Send user messages via chat/prompt request.
  • Clear chat and Reset chat.
  • Support receive chat contents via chat/contentReceived notification.
  • Present and allow user change behaviors and models returned from initialize request.
  • Present and add contexts via chat/queryContext request
  • Support tools contents: run/approval/reject via chat/toolCallApprove or chat/toolCallReject.
  • Support reason/thoughts content blocks.
  • Show MCPs summary (running, failed, pending).
  • Support chat commands (/) auto completion, querying via chat/queryCommands.
  • Show usage (costs/tokens) from usage content blocks.
  • keybindings: navigate through chat blocks/messages, clear chat.
• MCP
  • Open MCP details window
  • Receive MCP server updates and update chat and mcp-details ux.
• Basic plugin/extension documentation

I have low experience to create vscode plugins, so without help this takes more time.

Any help is welcome, please report in this issue for alignment

I finished implementing full support for vscode, supporting everything that ECA supports ATM.
