fix(cli/runtime): key dependency-staleness on corePath, not only the pyproject hash#104

…pyproject hash The managed Python venv is a single global path (~/.openant/venv) shared by every worktree. The staleness check (depsStalenessAt) keyed only on pyproject.toml content, so two worktrees with identical pyproject.toml were considered "up to date" even though the venv's editable install (`pip install -e <corePath>`) pointed at whichever worktree installed last -- a binary built in worktree B would silently import worktree A's Python source. Introduce depsHash(corePath) = sha256(corePath + "\0" + pyproject.toml contents) and use it for both the install baseline stamp and the staleness comparison. A change of corePath (switching worktrees) now reads as stale and triggers a reinstall that re-points the editable install at the active source. (hashFile remains a tested file-hash utility, no longer on the staleness path.) Tests: internal/python/runtime_corepath_test.go (two worktrees with byte-identical pyproject but different corePath -> the second is detected as stale; same corePath -> not stale). RED 1 failed -> GREEN; go test ./internal/python/ ok (existing staleness + hashFile tests unaffected); gofmt + vet clean. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
