MCP: drawing tools describe inherited paint and export text options

Omitted paint fields keep the current appearance, so agents can get a black outline when they only set a fill. Document the initial white fill and 1 pt black stroke and recommend explicit paint for outline-free art.

Clarify SVG/SVGZ outlineText versus PDF options.advanced.outlineText and PDF's live-text default, noting DXF also accepts the top-level flag. Descriptions and documentation only; drawing and export behavior are unchanged.
