-- Omni/Ci.sh used "${CODEROOT:?}"/**/* which relies on bash globbing.
-- Omni/Lint.hs recursively checks if passed directory or uses git diff if no args.
-- But Omni/Ci.sh passes **/*.
-- Let's try passing the root directory or just run it without args?
-- Omni/Lint.hs says:
-- "case Cli.getAllArgs args (Cli.argument "file") of [] -> changedFiles ..."
-- So if we pass nothing, it only checks changed files.
-- The CI script explicitly passed everything.
-- We can replicate "everything" by passing the coderoot, assuming Lint handles directories recursively?
-- Omni/Lint.hs: "traverse Directory.makeAbsolute /> map (Namespace.fromPath root) ... filter (not <. Namespace.isCab)"
-- It seems it expects files.
-- We can use `git ls-files` to get all files.

-- If we want to check everything, maybe we should implement a "check all" mode in Lint or pass chunks.
-- However, looking at Omni/Ci.sh: `"$runlint" "${CODEROOT:?}"/**/*`
-- This globbing is handled by the shell. It might be huge.
-- If I run `lint` with `.` it might work if Lint supports directories.
-- Omni/Lint.hs: "files |> ... filterM Directory.doesFileExist"
-- It seems it filters for files.
-- If I pass a directory, `doesFileExist` will return False.
-- So I must pass files.
-- Let's pass all files from git ls-files.
-- But we must be careful about ARG_MAX.
-- For now, let's try passing them. If it fails, we might need to batch.
