ci: auto-post CI-built Android APK to Telegram on every release tag

New `telegram:` job in release.yml downloads the Android artifact
uploaded by the `android:` job, posts the APK with a short caption
(Telegram caps captions at 1024 chars, we blow past that), then
replies with the full changelog in two quote blocks — Persian first,
English second — matching the format the user wants.

Changelog content lives in `docs/changelog/v<tag>.md`. The file has
a comment header explaining the format, then:
  - Persian bullets
  - a bare `---` separator line
  - English bullets
The workflow splits on that separator. No emojis. Missing changelog
file = the reply is skipped (doc post still lands).

Telegram credentials come from repo secrets:
  TELEGRAM_BOT_TOKEN  (set)
  TELEGRAM_CHAT_ID    (set)
Missing either = job logs a notice and returns 0. A forker who hasn't
set up Telegram gets a clean release with no notify attempt.

Also includes v1.1.0's changelog file so the first run of this job
has something to post.

+Telegram changelog posted automatically by .github/workflows/release.yml
+on every tag push. Format:
+  - Persian changelog first (goes in an HTML <blockquote>)
+  - A separator line of just `---`
+  - English changelog second (also in a <blockquote>)
+  - Leave ASCII `-`, digits, and "issue #NN" refs as-is
+
+The workflow splits on the `---` separator. Bullets can be whatever
+you like; the bot forwards verbatim.
