Module progress 

Text progress bar builtins backed by the indicatif crate.

R’s utils::txtProgressBar API lets scripts report progress for long-running operations. This module stores progress bar state on the Interpreter struct as a Vec<Option<ProgressBarState>> — each bar is addressed by its index in this Vec. The R side sees an integer ID with class "txtProgressBar".

Builtins:

• txtProgressBar(min, max, style) — create a bar, return integer ID
• setTxtProgressBar(pb, value) — update the bar’s position
• getTxtProgressBar(pb) — return the bar’s current value
• close(pb) — finish and remove the bar (dispatched from the connection-layer close() when the argument has class "txtProgressBar")

Structs
