* fix(is-git-repo): recognize bare repositories
is_git_repo() used `git rev-parse --show-toplevel` to detect whether
the current directory is inside a git repository. --show-toplevel
fails for bare repositories since they have no working tree, so every
command that relies on this shared helper (e.g. `git browse`) reports
"Not a git repo!" when run from inside a bare repo, even though it
plainly is one.
Switch to `git rev-parse --git-dir`, which succeeds for both normal
and bare repositories and keeps the existing "not a repo" behavior
for non-repo directories.
Fixes#1238, reported and LGTM'd by maintainers there with this exact
fix; no PR had been opened for it yet.
Adds tests/is-git-repo.bats covering: a normal repo, a bare repo, and
a plain (non-repo) directory.
* Fix ruff lint failures in scripts/checkstyle.py
This PR's new Ruff CI job surfaced pre-existing style issues (unsorted
imports, deprecated typing.List/Dict, nested ifs, bare exit()) in
checkstyle.py. Cleaned these up so the newly added lint job passes.
