feat: make overlay caption bubble width fixed and left-align text

Browse Source 
Set a fixed width on the caption bubble via `gtk_widget_set_size_request()` using
the effective width parameter, and change label alignment from center to left with
fill halign. Update the `--overlay-max-width` help text and README description to
reflect the new fixed-width behavior (still capped at 80% of monitor width).
