studio/chat: friendly English-word names for auto-created containers

Replaces the "chat-<thread-id-slug>" auto-name with a random
English-word + short hex suffix (e.g. "kestrel-3f9c"). Applies only
to the chat-adapter's lazy-create path; the OpenAI container_auto
path stays unnamed (only fires when no custom TTL is set).

+/**
+ * Friendly default names for auto-created OpenAI shell containers.
+ * Used by the chat-adapter when the lazy-create path fires (Code pill
+ * on, no thread container yet, user has set a non-default TTL). The
+ * goal is a human-memorable label like "otter" or "harbor" instead of
+ * "chat-abc12345" — the user can still rename via the Studio-side
+ * alias map.
+ *
+ * The list is curated to:
+ *   - Be unambiguous, non-offensive nouns from natural categories
+ *     (animals, plants, geography, materials, weather).
+ *   - Avoid technical / political / brand words that might read as
+ *     odd in a chat UI.
+ *   - Stay reasonably small so the bundle cost is negligible (~200
+ *     entries × ~7 bytes ≈ 1.5 KB).
+ *
+ * Collisions are tolerated — the container's real unique key is its
+ * ``cntr_*`` id, not its name. A short random hex suffix is appended
+ * to make accidental same-name collisions visually distinct in the
+ * picker list.
