[Cursor AI] Add studio status monitoring node

[ewels]

A new seqera-studios-monitor node was introduced to monitor Seqera Studio session status, mirroring the functionality of the existing workflow monitor node.

• The nodes/studios-monitor.js runtime polls the GET /studios/{sessionId} API endpoint.
  • It maps Studio statuses (e.g., starting, running, stopped, errored) to distinct output ports (active, stopped, error) and visual indicators (color, shape).
  • Supports dynamic polling intervals, an optional workspace ID override, and a keepPolling flag to continue monitoring until a terminal state is reached.
• The nodes/studios-monitor.html file provides the editor UI for configuring the Studio ID, workspace ID, and polling settings, along with comprehensive help documentation.
• The node is registered in package.json under seqera-studios-monitor, and the package version was incremented to 1.0.2.
