Don't answer @ai questions that get a badword warning

 ## [Unreleased]
 ### Added
 - `@ai <question>` in a channel: the AI (Cloudflare Workers AI, `ai_chat.py`) answers in that channel, as short plain text for screen readers, followed by `AI_CHAT_DISCLAIMER` ("AI bisa salah. Periksa kembali info penting."). It remembers the channel's last few questions for follow-ups, never gets nicknames, and has a per-person cooldown and a daily limit; answers with clear badwords are replaced by a refusal. Off by default (`/abt aichat`); users can read `/help ai`.
-- Optional AI context check (`ai_review.py`, Cloudflare Workers AI): when every badword in a message is an ambiguous one (`AI_AMBIGUOUS_WORDS`, e.g. anjing, babi, tahi, telanjang, gay), the bot asks the AI whether it was an insult instead of counting it right away, so "anjing tetanggaku berisik" is not punished but "anjing lah" is. The AI also sees up to `AI_CONTEXT_MESSAGES` earlier messages and two follow-ups (kept in memory only, without names), so a lone "anjing" after "aku punya binatang baru" is read as the pet. Runs in the background; if the AI does not answer the message is not counted. Off by default, switched with `/abt ai` (refused until the credentials are in `config.json`); `/bwt` shows the AI's verdict; `tools/ai_eval.py` measures a model on 38 labelled sentences. Setup: `docs/ai.md`.

Setup: `docs/ai.md`.
 - GitHub Actions workflow (`.github/workflows/deploy.yml`): pull requests into `main` are checked (all Python files must compile), and merging into `main` updates and restarts the bot on the server over SSH through `tools/deploy.sh`, using a key that can only run that script. Setup: `docs/deploy.md`.
 
 ### Fixed
+- An `@ai` question with a badword (`@ai anjing`) got a badword warning and was still answered by the AI. A question that gets a warning is no longer answered. With `/abt ai on`, a question with only ambiguous words is judged by the AI right away (no wait for follow-ups) and the AI is told it is a question to the assistant: asking about a word is not counted and is answered, insulting someone in the question is counted and is not answered.
 - Anyone logged in with a shared account (e.g. `murid`) could delete that account for everyone with `/du murid` + `y`, because the bot treated it as deleting their own account. Accounts listed in the new `SHARED_ACCOUNTS` setting (default `tamu`, `murid`, `hadirin`, `osis`, `guest`) cannot be deleted via the bot, not even by admins.
 - Join/login spam detection counted everyone on a shared account behind one IP (all students on `murid` from the school network) as one person. For shared accounts it now tells people apart by nickname + IP.
 - Channels created by a shared account (owned by e.g. `murid`) could be deleted or given away by anyone on that account. Non-admin shared accounts can no longer create, delete or transfer channels via the bot; admin accounts (`pemateri`, `F.OSIS`) keep their admin rights. `pemateri` and `f.osis` are in the default `SHARED_ACCOUNTS`.
