conjurer: deploy bot on its own [deploy]-gated image channel

The production bot now tracks conjurer-bot-deploy instead of conjurer-bot,
so it updates only when the conjurer CI promotes a build (commit message
contains [deploy]). Adds the image-updater 'deploy-bot' alias and the
kustomization images entry for it; DEPLOY-BOT.md documents the channel and
the one-time bootstrap. Test bot + librarian keep tracking every build.

Pairs with conjurer#20 (the CI promotion step).

## Update channel — only on `[deploy]`
Unlike the test bot (which tracks every build), the production bot updates **only
when you promote a version**. It runs a **separate image**,
`conjurer-bot-deploy`, which the conjurer CI tags **only when the commit message
contains `[deploy]`** (it re-tags the already-built `conjurer-bot:<sha>` — same
bytes). The image-updater's `deploy-bot` alias then bumps this bot's tag.
So: normal commits update the test bot + librarian; a commit with `[deploy]` in
its message is the one that also rolls the production bot.
**Already bootstrapped:** the channel was seeded by the first `[deploy]` commit
(the merge of conjurer#20), which promoted `conjurer-bot-deploy:fbd1ec9f` — the
tag pinned in `kustomization.yaml`. From here the image-updater keeps it current
on each future `[deploy]` commit. Note the librarian is shared and still tracks
latest, so mind large bot⇄librarian version skews.
If you ever need to seed a tag by hand:
```bash
docker pull gitea.czernobog.pl/gitea/conjurer-bot:<sha>
docker tag gitea.czernobog.pl/gitea/conjurer-bot:<sha> \
gitea.czernobog.pl/gitea/conjurer-bot-deploy:<sha>
docker push gitea.czernobog.pl/gitea/conjurer-bot-deploy:<sha>
