What's New in v0.6.1

Syntax → Builder tab now renders the diagram. Typing lavaan syntax in the Syntax tab and clicking Builder produced a blank canvas. Root cause: generateCanvasFromSyntax() existed but was never called on tab switch. showCanvasMode('builder') now reads the syntax textarea and invokes it before triggering resize() → draw().

Structural paths (~) now draw regardless of line order. Rewrote generateCanvasFromSyntax to two passes: Pass 1 creates all LV + indicator nodes from =~ lines; Pass 2 processes ~ lines with all nodes guaranteed to exist. Any label referenced in ~ but absent from =~ is auto-created as an LV node.

Inline comments (# ...) are now stripped from syntax before parsing, so annotated syntax files parse cleanly.

Free-parameter prefixes (e.g. 0.5*x1, 1*x2) are stripped from indicator and predictor labels during canvas generation.

Removed dead code from showCanvasMode syntax branch.
