Adds focused regression coverage for successful empty atomic writes. The test replaces existing nonempty content with an empty string and verifies that no temporary file remains.\n\nThis detects a strict-to-loose false comparison mutation: file_put_contents() returns integer 0 for a successful zero-byte write, which MUST NOT be treated as failure.
