The "Dim line color" row on Leader and Dimension entities was read-only: an earlier attempt wired it to Leader.override_color, which acadrust never serialises, so the pick was lost on save. Store it instead as a standard ACAD_DSTYLE per-object dimension-style override (DXF code 176, an ACI index) through the existing dim_override codec, so it round-trips through both DWG and DXF like the other dim overrides. RGB picks collapse to the nearest ACI, matching the rest of the dim-colour stack (dimension styles are index-only through the file layer). The renderer prefers the override over the style's DIMCLRD. The write branch is guarded to leaders and dimensions so a mixed selection cannot stamp the override onto other entity types. Bumps acadrust to c9fe982, which carries parsed XDATA onto dimensions on DXF read (it was dropping common.extended_data), so the dimension override persists on DXF save as well as DWG.
