Add font ligature rendering support

Browse source 
Add tweak.ligatures option (default: no) for OpenType liga/calt
rendering with programming fonts. Ligatures are render-only —
the grid and copy/paste are unchanged.

Uses fcft_rasterize_shaped_run() to shape full runs with
HarfBuzz and render each glyph by its shaped glyph ID,
correctly handling contextual alternates and ligatures.

Block cursor over a ligature uses a pixman gradient as composite
source for single-pass correct-color rendering.
