Subject: [PATCH] fix: discover Gitea update source from release notes (no
 hardcode)

Gitea URL removed from source code. UpdateChecker now only hardcodes
GitHub API; the Gitea mirror URL is embedded in release notes as an
HTML comment (<!-- update-source: ... -->) and discovered at runtime.
Keeps self-hosted server address out of the public codebase.

version 1.8.0 -> 1.8.1 (code 17 -> 18)
