ResolveRepositoryRoot accepts an optional stopBoundary parameter that
caps the upward walk; production callers pass null and behavior is
unchanged. The two repository-marker tests now seal their walkers
inside their own temp directories, so a redirected TMP or a co-located
C:\src checkout no longer leaks ambient marker-bearing ancestors into
the assertion.
Regression test ResolveRepositoryRoot_StopBoundary_IsolatesWalkerFromAmbientAncestorMarkers
constructs an outer ancestor that carries src/ + .git, confirms the
walker leaks into it without the boundary, then asserts the same call
throws with the boundary supplied.
