The options system mirrors pandas.get_option /
pandas.set_option. It manages display, mode, and compute settings with full
validation support.
Read, write, and restore option values by dot-separated key.
Pretty-print documentation for one or all options.
Temporarily override options and restore them with enter() / exit().
Access options via a deeply-nested proxy object for ergonomic reads and writes.
Extend the registry with application-specific options, including custom validators.
