feat: focus the target embedded chat when a button delivers a prompt

[RAIT-09]

Description

Agent buttons with viewType: embedded delivered the prompt to the nearest chat block but did nothing visually — every other viewType opens, reveals, and focuses its target. In a long note with the block off-screen, clicking the button looked like nothing happened, even though the prompt had landed in the (invisible) block.

The embedded branch of runPromptInChat now focuses the resolved target before delivery, reusing the container focus() — the same path the Session Manager uses — which scrolls to the block and focuses its input (and fronts the host tab when needed). All of its failure paths degrade silently to the previous deliver-only behavior. The viewType: embedded doc tip mentions the scrolling now.

If someone later wants delivery without the scroll jump, an opt-out fence option can gate this single call — deliberately not added until requested.

Poem

A rabbit hops where chat blocks hide,
Finds the nearest one inside.
The prompt arrives, the view gains sight,
It scrolls and focuses—just right!
“Now type away,” the bunny cheers.
