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.
