lensline v2.1.0

Added

• Per-highlight support: Different highlight groups per provider and per result, instead of one global style.highlight
  • Provider-level: set highlight = "SomeHl" in provider config to color all its results
  • Result-level: provider callbacks can return highlight per item to override the provider highlight
  • Fallback chain: result highlight → provider config highlight → global style.highlight
  • Separator and prefix always use global style.highlight
  • Fully backward compatible — existing configs without highlight customization behave identically

Fixed

• Faster startup time and more efficient caching by replacing gitignored caching from eager & bulk to lazy and per-file
