P11.5 + B2.1/B2.2: per-command units + description (where applicable)

Adds  to scalar setters whose payloads are
plain numbers OR {value, unit}. Skipped where payload is compound or
mode-dependent (control-%, {F, C: [...]}, etc.) — documented inline.
Every command gains a description field for wikiGen consumption.
