zio fork: @ staff chat while gagged, gag message with time left and reason

Gagged or silenced players can still send @ team chat to online staff. The chat-blocked message
now says how long the gag or silence has left, or that it's permanent, and why. Reasons are kept in
memory alongside each penalty. Adds release.sh, which ships CS2-SimpleAdmin.dll and lang/en.json.

+# zio.sh fork
+
+This is zio.sh's fork of CS2-SimpleAdmin 1.8.2b (`upstream` is daffyyyy/CS2-SimpleAdmin, branched
+from the `build-1.8.2b` tag). Changes, all marked `zio:` in the code:
+
+- A gagged or silenced player can still send `@message` in team chat to reach online staff.
+- The gag/silence chat message says how long is left (or that it's permanent) and the reason, in
+  place of "Your chat is blocked to: <end date>". New lang keys `sa_player_penalty_gag_active`,
+  `..._gag_active_perm`, `..._silence_active`, `..._silence_active_perm` and
+  `sa_player_penalty_no_reason`, in `lang/en.json` only (other languages fall back to it).
+
+Publish with `FORGEJO_TOKEN=... ./release.sh v<ModuleVersion>` (ModuleVersion is `1.8.2b-zioN`).
+It rebuilds from the committed source and uploads `SimpleAdmin-<tag>.tar.gz` to git.zio.sh
+(`cs2/SimpleAdmin`), holding only `CS2-SimpleAdmin.dll` and `lang/en.json`. The rest of the plugin
+and `shared/CS2-SimpleAdminApi` stay as the upstream 1.8.2b release installed them.
