* refactor: Extract shared cooldown helpers to package-level functions * feat: Add PyPI cooldown handler with PEP 691 file parsing * feat: Add PyPI cooldown file stripping logic * feat: Implement PyPI cooldown HandleMetadataRequest with PEP 691 filtering * feat: Wire PyPI cooldown into pypi_registry interceptor * update headers for no cache * fix: Strip conditional GET headers to prevent 304 bypass in cooldown handlers pip and npm clients cache Simple API / registry responses with ETags. On subsequent requests they send If-None-Match, which causes the server to return 304 Not Modified with no body. The cooldown response modifier received an empty body, failed to parse it, and failed-open — letting the client use its stale cached (unfiltered) response. Fix: delete If-None-Match and If-Modified-Since from the request before forwarding, forcing a full 200 response so the modifier always has a body to filter. Also removes the Content-Type guard from the PyPI modifier (the empty Content-Type on 304 responses was a symptom of the same root cause) and replaces Cache-Control: no-cache with the more targeted header deletion. * docs: Add PyPI cooldown limitation for pip < 22.3 to dependency-cooldown docs
