v0.4.7 — --compare flag, CI traceability

What's new in v0.4.7

Added

• --compare on audit-sb3 and audit-cleanrl: Auto-generate comparison.html against any previous audit — no need to run the full fix pipeline.

  deltatau-audit audit-sb3 --algo ppo --model fixed.zip --env HalfCheetah-v5 \
    --compare before_audit/summary.json --out after_audit/
  # → writes after_audit/comparison.html

• _version + _timestamp in ci_summary.json: CI output now includes audit tool version and timestamp, matching summary.json.

• README: --compare docs, --workers/--seed in fix-sb3 options.

• 9 new tests (191 total).
