Measure the non-interactive parts of the theme switcher:
- theme preview index build (omarchy-theme-switcher before UI handoff)
- image selector row/thumbnail cache prep (omarchy-menu-images --cache-only)
- lazy selector row prep used by the interactive theme switcher
- full thumbnail cache warmup cost (omarchy-menu-images --cache-only)
Options:
--repeat=<count> Number of warm runs to measure for each case (default: 5)
