I hop through lines and nudge a key,
Eight dons Denops, light and free.
Workflows shift and badges gleam,
Config trimmed to tighter seam.
Thump — a rabbit's tiny beam 🐇✨

[lambdalisue]

lovell/detect-libc#33 will fix the issue on Linux (but on Windows)

[lambdalisue]

CI fails because of coverage generation (denoland/deno#30924) so merge.
