v0.7.0

Added

• Terminal ANSI colors (color0–color15) can now be overridden individually
  via ansi_colors.* in config.json, layered on top of the active theme
  preset — with a color picker per slot under Settings → Appearance → ANSI
  Colors. Malformed values are ignored, and clearing an override falls back to
  the preset's palette. (#37)

• Font ligatures can now be enabled for terminal text. A new optional
  font_features config passes OpenType features (e.g. {"calt": true})
  through to the renderer, and Settings → Appearance grows a toggle for the
  common calt/liga pair. Ligatures stay disabled by default for cell-grid
  safety, and changes hot-apply to open panes. (#38)

Fixed

• Ctrl+L now clears the screen while the prompt-local line editor is active.
  The readline dispatcher used to swallow it as an unrecognized chord; it now
  forwards the same form-feed byte the raw terminal path sends, so the shell
  repaints its prompt as expected. (#36)
