Description

I think we should expose line join settings for all layers drawing line or polygon-like shapes.

Currently the line join defaults to mitre for vegalite, but I think we should take control over this setting.
I'm imagining something like

DRAW path SETTING linejoin => 'round'

Or when numeric, it can imply linejoin => 'mitre' and simulateously set the mitre limit.

DRAW path SETTING linejoin => 10

Research direction

The issue names no files, tests, or entry points; start by tracing how line and polygon-like layers are translated into Vega-Lite drawing settings. Define how string and numeric linejoin values should apply across all relevant layers, then verify that the generated visualization uses the requested join style and mitre limit.
