… Identity (#3345)

## Stack

Depends on the recommended-agent core in
[#3344](#3344). This PR adds the
setup controls and agent-card presentation.

## What changes

Builds with a recommendation offer **Automatic** and **Custom** in
Create agent and the Identity settings for local agents. Builds without
a recommendation keep the existing controls.

- **Automatic** selects the recommended harness, model and thinking
level. The closed settings row shows **Set to [model] (recommended)**;
the model truncates on one line while the parenthetical remains visible.
- The Automatic option puts the recommender before the optional
description, with the active model details beneath it. Attribution and
description come from configuration; the shared default makes no promise
about cost or update frequency.
- The settings icon gently cycles between the AI icon and active harness
logo. Custom and reduced-motion settings use a static harness logo.
- When no recommended setup is usable, **Custom remains available**,
including hosted-agent creation. Automatic still requires a usable
recommendation.
- **Custom** reveals the existing Harness, Model and Thinking controls
in place. Its closed row omits the redundant model byline. Choosing
model, provider or thinking settings in Identity turns Automatic off.
- On the **Agents page**, Automatic agents show their model’s display
name followed by **(Automatic)** beside the cycling icon. This is a
read-only detail aligned with the other cards’ model rows and uses the
default text color.
- In chat, Automatic agents keep session controls while model and
thinking controls are hidden. Custom agents keep their existing
controls.

The recommendation setting accepts the existing candidates array or an
object containing `candidates`, optional `recommendedBy`, and optional
`description`. Attribution stays with the current recommendation rather
than being copied into saved agents. Hosted agent types retain their own
settings.

## Validation

Current head: `ee16e32f3885cdf374fb3508d7c58d9bc4462923`, rebased onto
the updated core. [Current-head
review](#3345 (review))
confirms the four UI commits are patch-identical to the previously
approved stack and reports **1,068 passed, one skipped** across eleven
affected component/config/service suites. [Hosted CI
passed](https://github.com/block/buzz-app/actions/runs/43534228146) on
this exact head, including `CI required`.

Local behavior evidence at `4d5014295583e185716ac3e49249e7b1e43f0645`:

- Related component/service checks: **1,033 passed, one existing skip**
across nine files, combining initial passes with final reruns of
affected files; this is not a single combined run. Includes Custom →
hosted harness → introduction → creation when no recommendation is
usable.
- Both TypeScript projects and mandatory pre-push related-unit/design
checks passed.
- Four Chromium/WebKit fixture checks passed, exercising narrow/wide
layout in both themes: model truncation, visible recommendation suffix,
and separation of description/model details. These establish browser
layout, not native acceptance.
- One browser geometry case was added because DOM-emulated tests cannot
prove wrapping/truncation. No browser cases were removed. Existing mode,
settings-retention and fallback assertions remain; stale label
assertions were updated for Custom and the new summary.
- Test-volume audit: changed files contain 841 → 848 named test
declarations (parameterized runtime cases counted separately). Tests
account for +1,558/−30 lines versus +1,221/−216 non-test lines in this
PR, so test changes exceed half the diff. The audit retained distinct
parser, metadata, host-wiring and recovery coverage.

At `fd3ee535098e7c411852ba847cce01911b29ba23`, the running macOS desktop
build was exercised through the Agents page and Automatic → Custom mode
switching in an unsaved Create draft. The draft was closed without
creating or changing an agent. This verifies the captured native
rendering and mode transition; broader native states are not covered by
these captures. The full Biome check and mandatory push hooks also
passed on that pre-rebase head.
