`test_fresh_palace_via_full_stack_gets_cosine` used `tempfile.Temporary-
Directory()` as a context manager, which tries to delete the temp path
on exit. On Windows, ChromaDB still holds SQLite file handles to
`chroma.sqlite3` when the context closes, producing:
PermissionError: [WinError 32] The process cannot access the file
because it is being used by another process: '...\\chroma.sqlite3'
NotADirectoryError: [WinError 267] The directory name is invalid
Other tests in the same file use pytest's `tmp_path` fixture, which
defers cleanup to session end (when the process is exiting and the
file-lock contention is moot). Align this one with the rest of the
file.
CLAUDE.md already documents the 80% Windows coverage allowance due to
"ChromaDB file lock cleanup" — the fix is to stop fighting the lock.
