Migrate permission system from MCP file-based to stdio-based

Replace MCP permission server with stdio-based permission flow that
communicates directly with Claude CLI via stdin/stdout. This simplifies
the architecture and fixes permission expiration issues.

Key changes:
- Use --permission-prompt-tool stdio and --input-format stream-json
- Handle control_request messages for permission prompts
- Send control_response via stdin to approve/deny
- Check local permissions for auto-approval of pre-approved tools
- Only expire pending permissions when VS Code restarts, not panel close
