Replace the busted-based Lua test runner with a repo-local harness. The new harness runs spec files directly under `nvim -ll`, ships its own reporter and lightweight `luassert` shim, and keeps the helper/preload flow used by the functional and unit test suites. Keep the file boundary model shallow and busted-like by restoring `_G`, `package.loaded`, `package.preload`, `arg`, and the process environment between files, without carrying extra reset APIs or custom assertion machinery. Update the build and test entrypoints to use the new runner, add black-box coverage for the harness itself, and drop the bundled busted/luacheck dependency path. AI-assisted: Codex
