The fix introduced in #161 is incorrect, it sets prog-fill-reindent-defun to the default implementation which doesn't use Tree-sitter at all. The issue was in the way we used to set treesit-defun-type-regexp. Any top-level expression was considered a defun. This commit changes the predicate lambda, so only the direct children of "source" node are considered as defun's and additionally, if clojure-ts-toplevel-inside-comment-form is true, the direct children of the rich comment forms.

Emacs 32 now refuses setting variables with :set function from .dir-locals.el if setter doesn't support 3-arguments arity. This is actually visible in the CI logs from the main branch (https://github.com/clojure-emacs/clojure-ts-mode/actions/runs/41298557092/job/124824528357):

[22](https://github.com/clojure-emacs/clojure-ts-mode/actions/runs/41298557092/job/124824528357#step:5:123)
options set in .dir-locals.el
  should apply to the buffers in the directory, and only to those (14.88ms)
Warning (emacs): The setter of clojure-ts-indent-style lacks support for setopt-local
Warning (emacs): The setter of clojure-ts-extra-def-forms lacks support for setopt-local
Warning (emacs): The setter of clojure-ts-comment-macro-font-lock-body lacks support for setopt-local

But I'm not sure why tests pass on main.

Another issue was that clojure-ts--apply-local-variables didn't set indent-region-function according to clojure-ts-align-forms-automatically value, so clojure-ts-align-forms-automatically didn't have any effect in .dir-locals.el and indent-region-function was always set to default treesit-indent-region.
