TEST BUILD — old-api CSRF fix (not for general use)

⚠️ UNOFFICIAL TEST BUILD — not for general use.

Built from the old-api branch (commit 10688fc) to verify a fix for
myepisodes.com's CSRF protection, which now rejects the legacy addon's
login/search/add/watch requests with 403 Request could not be verified.

This is a one-off verification package, not a normal versioned release:

• addon version is 3.2.1~test1
• addon name/summary are prefixed "TEST BUILD" so it's obviously distinct
  from the real addon in Kodi's addon browser
• not submitted to the official Kodi repo, not endorsed by the upstream
  author

Verified live against myepisodes.com with the project's own test account;
full pytest suite passes. See the old-api branch commit message for
technical details.
