fix: auto-format git add -A stages all changes, not just formatted files

[tsavo-at-pieces]

Problem

The auto-format job in ci.skeleton.yaml line 70 uses git add -A after running dart format --line-length X lib/. This stages all changes in the working directory, not just the files that dart format modified.

Impact

• If any other process modified files between checkout and format, those changes get committed as "bot(format)"
• If .g.dart files exist and dart format reformats them, they get included in the bot commit
• Any file drift from the checkout ref gets silently committed

Current behavior (ci.skeleton.yaml line 68-70):

git add -A
git commit -m "bot(format): apply dart format --line-length <%line_length%> [skip ci]"

Expected behavior:

Only stage files that dart format actually changed:

git diff --name-only | xargs git add
git commit -m "bot(format): apply dart format --line-length <%line_length%> [skip ci]"

Or more precisely, only add lib/ Dart files:

git add lib/

Fix Plan

• Replace git add -A with git add lib/ in the auto-format step of ci.skeleton.yaml
• Update both the generated ci.yaml for this repo

Fix submitted in PR #28

Changed git add -A → git add lib/ in templates/github/workflows/ci.skeleton.yaml line 70.

This scopes the auto-format commit to only stage files in lib/ (the same directory dart format operates on), preventing unrelated workspace files from being accidentally committed by the format bot.
