bflatasticandClaude Opus 5.5 92cadd6083 M8.3: Liquify Tool Options dialogs, pen pressure and Brush Affects
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.

//! Every-command sweep: each registered command, in three fixture states, with `{}` and with fuzzed
//! junk params, must return Ok or Err (never panic), never leave an interaction open, and never
//! corrupt the tree.
// Integration tests: unwrapping and panicking on failure is fine here, unlike in shipped code (AGENTS.md › Robustness).
