Detailed Description

Visual query builder that composes a multi-condition AND filter.

The user picks a scope (Nodes or Edges), then adds one or more condition rows (key / operator / value). Clicking Apply emits userChoices(GraphQuery) with all conditions carrying the chosen scope. The caller applies the filter and adds a single chip to the bar.

Implemented in pure C++ (no .ui file) so condition rows can be added and removed dynamically without UIC constraints.
