Double-clicking a Liquify tool opens its Tool Options (dialog liquifyOptions):
the shared Global Brush Dimensions (Width, Height, Angle, Intensity, Use
Pressure Pen), the tool's options (Detail, Simplify with its checkbox, Twirl
Rate, Complexity, Brush Affects, Horizontal/Vertical) and Show Brush Size.
The canvas captures pen pressure from pen/touch force, ui.pointer and MCP
pointer events take `pressure`, and object.liquify takes [x, y, pressure].
Fixes: LiquifyParams::to_json now sends affectAnchors/In/Out; Alt-drag sizes
the brush from its current size (Shift keeps proportions) instead of
collapsing it. Hint-bar text for the seven tools. Registers the MCP Liquify
tests file added in M8.2.

Each tool keeps its options (a table in vectorcraft_tools::settings) when another
tool is chosen, across document switches, and in the saved preferences
(Prefs::tool_settings). The 7 Liquify tools share one set of Global Brush
Dimensions; the Symbolism tools share their brush. tool.setOption takes
{values} and a `tool` (another tool's options are stored for later), returns
the options, and works headless (MCP host command).
