saphidandClaude Opus 5.5 2d63dacdf9 itch.io purchases: review fixes for redirects, key redaction, races and revoked keys
- Storage downloads no longer go through a "any host name" redirect policy.
  _web.public_apk resolves each hop, refuses loopback, private, link-local,
  shared, reserved and multicast addresses (odd IPv4 spellings and IPv4
  mapped into IPv6 included), connects to the checked address, and checks
  again on every redirect. No credentials are sent there. _web.ANY and the
  extra open_url/apk parameters are gone; _web.apk's streaming is shared as
  save_apk.
- api.itch.io redirects are no longer followed with the key: the download
  step reads a 30x Location, a JSON body's url, or takes the file itself,
  since the live response is unverified.
- Error text loses the key, and any start of it from 8 characters, before
  joining and truncating.
- Saving and deleting the key are serialised; a connect whose /profile check
  finishes after a disconnect (or another connect) does not save. The key
  file is written through a unique mkstemp file.
- 401/403 from api.itch.io deletes the key only once /profile confirms the
  key itself is refused, including at download time with cached metadata.
  Storage-host 403s are download errors, not rate limits.
- Docs list which parts are verified against the public reference and which
  are assumed or unknown without a live account.
