Problem

canola.nvim's default hidden file filter only matches dotfile patterns (^%.). Users who work in git repos want smarter filtering: show tracked dotfiles, hide ignored non-dotfiles. This was previously done inline in user configs via is_hidden_file + git ls-files/git ls-tree, but that approach doesn't scale and requires runtime setter calls.

Solution

Add a canola-git extension to canola-collection that provides git-aware hidden file filtering. On CanolaEnter/refresh, it runs git ls-files --ignored --exclude-standard --others --directory and git ls-tree HEAD --name-only for the current directory, caches the results per-directory, and overrides config._is_hidden_file with a function that:

For dotfiles: hides them only if they're not tracked
For non-dotfiles: hides them only if they're git-ignored

The cache is invalidated on refresh. Configuration via vim.g.canola_git.

## Problem canola.nvim's default hidden file filter only matches dotfile patterns (`^%.`). Users who work in git repos want smarter filtering: show tracked dotfiles, hide ignored non-dotfiles. This was previously done inline in user configs via `is_hidden_file` + `git ls-files`/`git ls-tree`, but that approach doesn't scale and requires runtime setter calls. ## Solution Add a `canola-git` extension to canola-collection that provides git-aware hidden file filtering. On `CanolaEnter`/refresh, it runs `git ls-files --ignored --exclude-standard --others --directory` and `git ls-tree HEAD --name-only` for the current directory, caches the results per-directory, and overrides `config._is_hidden_file` with a function that: - For dotfiles: hides them only if they're **not** tracked - For non-dotfiles: hides them only if they're git-ignored The cache is invalidated on refresh. Configuration via `vim.g.canola_git`.
