chameleon 4.4.46

Fixed

• dep_audit reported a false all-clear when the auditor never ran -- a security
  tool collapsing the two states it exists to distinguish. npm v7+ delivers
  auditor errors as PARSEABLE JSON ({"error":{"code":"ENOLOCK",...}} for a
  missing lockfile; the same channel carries every network/registry failure), and
  that body has neither metadata nor vulnerabilities, so it fell through to
  status:"ok" total:0. bundler-audit had the same class: a missing-lockfile run
  exits 0 with Could not find "Gemfile.lock" and zero advisory blocks, which
  also read as ok/0. A caller seeing status:"ok", total:0, findings:[]
  concluded "no known CVEs" when no audit had run. Both now degrade to the
  unavailable no-signal result the module docstring already promises: npm on an
  error body or any object missing both audit keys; bundler when zero advisories
  parse AND the clean-pass marker No vulnerabilities found is absent. A genuine
  clean audit (npm metadata with total 0, bundler's marker) still reads ok.
  Verified end-to-end on the fixtures: ts-nextjs -> unavailable: npm audit error: ENOLOCK, rb-rails -> unavailable: bundler-audit did not run cleanly.
• The python_format rules stanza dropped its parse warning. Every other tool
  stanza (tsconfig, eslint, rubocop) wires a parse_warning through to rules.json
  when the config is malformed AND emits a warning-only stanza when the config is
  broken-but-empty; python_format did neither, so a torn pyproject.toml /
  ruff / flake8 config parsed to no rules AND silently lost the signal that it was
  broken, reading as "no config declared". Mirrored the rubocop pattern exactly.
