* fix(reasoning-tags): strip MiniMax `mm:` namespaced reasoning tags
MiniMax M3 (e.g. via Fireworks) emits its chain-of-thought inline in the
content stream wrapped in `<mm:think>…</mm:think>` rather than in a separate
`reasoning_content` field. The reasoning-tag stripper only recognized the
`antml:` namespace, so `mm:`-namespaced tags slipped through QUICK_TAG_RE and
leaked the model's hidden reasoning into visible chat output.
Accept the `mm:` prefix alongside `antml:` in the shared sanitizer
(reasoning-tags.ts) and in the Telegram reasoning-lane coordinator's tag regex
and prefix list. Adds unit tests covering mm: think/thinking/thought blocks,
truncated-open orphan close recovery, and code-fence preservation.
