Problem: plenary.nvim is deprecated. The test suite depends on
plenary's async test runner and coroutine-based utilities, tying the
project to an unmaintained dependency. CI also tests against Neovim
0.8-0.11, which are no longer relevant.
Solution: replace plenary with busted + nlua (nvim -l). Convert all
async test patterns (a.wrap, a.util.sleep, a.util.scheduler) to
synchronous equivalents using vim.wait. Rename tests/ to spec/ to
follow busted convention. Replace the CI test matrix with
nvim-busted-action targeting stable/nightly only. Add .busted config,
luarocks test_dependencies, and update the nix devshell.
Problem: oil.nvim had no luarocks rockspec, so users of rocks.nvim
and similar tools could not install it from the registry. The stylua
CI action was also pinned to an older version.
Solution: add scm-1 rockspec and a luarocks publish workflow that
gates on tests passing before publishing on version tags. Bump
stylua action from v2.0.2 to v2.1.0.
Closes: barrettruth/oil.nvim#14
