## Problem
A single Assistant response often produces 10+ reasoning and lookup rows
("Reasoned", "Ran search_docs", …). They push the answer down the chat,
use raw tool names, and a fast tool call flashes past before the row
goes back to "Thinking...".
## Solution
Consecutive reasoning and lookup rows fold into one collapsible group.
- **Running:** the header shows a tool only while it executes ("Checking
policies in public..."). Between calls it reads "Thinking...", however
long that lasts. Each header label stays up for at least 1 second, so
quick calls no longer flash.
- **Finished:** the header lists what the tools did, e.g. "Searched docs
and checked policies", or "…, and 2 more".
- **Expanded (any time):** every call is listed under a vertical rule.
Rows still in progress shimmer, including several at once for parallel
calls.
## How to test
1. Run `pnpm dev:studio` and open the Assistant on a project with a few
tables.
2. Ask something that needs several lookups, e.g. "What RLS policies do
I have and what do the docs recommend for them?"
3. While it streams, check the collapsed header:
- It shows each tool while it runs, then goes back to "Thinking..."
between calls.
- Labels don't flash. Each stays up for about a second.
- Only the shimmer marks progress, with no blinking cursor underneath.
4. Expand the group mid-stream. Rows read like "Checking policies in
public..." rather than tool names, and only rows still in progress
shimmer.
5. When it finishes, the header lists the actions ("Searched docs and
checked policies") and stops shimmering.
6. Press Stop while a group is running. The unfinished row reads
"Response interrupted" and stops spinning.
7. Reload the chat. Older groups show their collapsed summaries.

## Summary by CodeRabbit
* **New Features**
* AI assistant tool activity is grouped into collapsible sections with
progress labels while work is underway and summaries when complete.
* Expand grouped activity to review reasoning and tool details. Active
tools and reasoning are highlighted, while completed reasoning without
text is hidden.
* Progress labels remain visible briefly during transitions, and active
responses display a shimmer effect.
* **Bug Fixes**
* The loading indicator no longer appears while the assistant is
processing a tool group.
