* fix(git): use git add -u in symlink .gsd fallback to prevent hang on large repos (#1977)
When .gsd is a symlink, nativeAddAllWithExclusions falls back from
pathspec exclusions (which git rejects with "beyond a symbolic link").
The previous fallback used nativeAddAll (git add -A), which traverses
the entire working tree — hanging indefinitely on repos with large
untracked data directories (444GB+ observed).
Change the fallback to git add -u, which only stages changes to
already-tracked files. This is O(tracked) instead of O(filesystem),
making it safe for repos with massive untracked trees.
The tradeoff — new untracked files are not staged in the symlink
fallback path — is acceptable because auto-commit primarily captures
changes the agent made to existing tracked files.
Regression of #1712 which introduced the symlink fallback but chose
git add -A. That fix assumed .gitignore covered all large directories,
but scientific/ML repos often have large untracked data dirs not in
.gitignore.
Fixes#1977

* chore: retrigger CI
* fix(test): update symlink autoCommit test to use tracked file modification
The PR changed the symlink fallback from git add -A to git add -u.
git add -u only stages changes to tracked files; untracked files are
skipped. The existing test created a new untracked file which git add -u
ignores, causing autoCommit to return null (nothing to commit).
Pre-commit the source file before the scenario and modify it so git add
-u can stage the tracked change.
