F-Droid repositories can now be added with HTTP basic auth, either as
https://user:pass@host/fdroid/repo (as F-Droid's client accepts) or with
separate username/password fields (store form, server API, and the CLI's
--username/--password-stdin). The login is stripped from the saved URL and
kept in a new shared module, apk_sources/_credentials.py, which writes
source-credentials.json in the data folder with mode 0600.
A credential is only ever added per request to its exact origin (scheme,
host, port): redirects elsewhere get nothing and have Authorization
removed. HTTPS only. 401 (or 403 with a login) on add gives a "check the
username and password" error and saves nothing; signature, pin, TOFU,
hash and rollback checks are unchanged. Removing a repository deletes its
login.
GitHub gets a user-settable token (FRAME_GITHUB_TOKEN still wins), sent as
Bearer only to api.github.com. If GitHub answers 401, the request is
retried once without it and the rejection is reported in source settings.
The source list shows only whether a token is set, never its value.
