build: pin the standalone validation harnesses to git revisions too

The ill-conditioned, masters-native and shared-provider harnesses used
path dependencies into references/; they now use the same pinned git
revisions as the workspace (gammaloop 474478a7, oneloopmaster 264a6ce,
Symbolica e679e8c1), so no manifest in the repository needs references/.
build_native.py rewrites those pins to its exported snapshots. All three
check from a clean environment. .claude/ (session worktrees) is ignored.
