[Feature] Support general GPIO skills

[IRONICBo]

Describe the feature

Background

The product should better support GPIO-based workflows that combine natural language interaction, pin control, persistent state, and scheduled execution.

Problem

The current experience is still oriented around one-off interactions, making it hard to manage repeatable GPIO operations such as timed switching, multi-step sequences, and stateful routines.

Proposal

Add support for:

1. natural language triggered GPIO actions
2. configurable GPIO read/write operations

Motivation

No response
