"""Extension handlers — new commands ported from the Rust fork.

Each function takes (action, voice) and returns nothing; it speaks via the
`speak` callback passed in from main.py. We keep the speech callback as
a module global to avoid passing it through every call site.

Usage from main.py:
    import extensions
    extensions.set_speak(_speak)
