User reported: switched to pro via /model, but assistant answers are still tagged with the flash model in the UI.

Repro (suspected):

1. Start a session on flash (or in bundle mode where flash is the default leg)
2. /model <pro-id> mid-session
3. Send a new message
4. The model pill on the resulting assistant card still reads as flash

Likely causes to check:

• The pill rendering uses a stale model id (bound at card-creation time and not updated when the active model changes)
• Bundle mode escalates flash → pro internally but the badge keeps showing the bundle's display name instead of the model that actually answered the turn
• State propagation from /model handler to the agent store isn't picked up by the card renderer

Relevant files: src/cli/ui/slash/handlers/model.ts, src/cli/ui/primitives/Pill.tsx, wherever the assistant card composes its header (likely under src/cli/ui/layout/).

The badge should reflect the model that actually produced that turn — not the model selected when the card was first opened, and not the bundle display name.
