Chinesezjc 5081697aaf feat(web): render bash tool output as a terminal card
The bash tool already declares the `card: 'terminal'` render intent for
both its call and its result, and host/connection/runtime already deliver
it to the browser as callView/resultView. The Web client ignored it:
rows derived from raw args, and the details panel flattened every tool's
content into one soft-wrapping `<pre>`. Column-aligned output folded into
a paragraph and a long listing stretched the panel without bound.

`TerminalBlock` (ui-primitives) renders a command as a terminal surface:
a shortened-cwd prompt line, output at `white-space: pre` in a
horizontally scrolling box, a head/tail height cap with an expand
control, an exit-code/signal status pill, and a copy control for the raw
output. ANSI SGR runs are parsed with `anser` and resolved onto `--dsw-*`
theme tokens, with literal rgb kept for values the design system has no
token for. Geometry and fonts mirror CodeBlock; the clipboard write both
need moved into a package-internal `clipboard.ts`.

Both Web render sites for a bash call consume the intent through one
derivation (`terminal-card-model.ts`), so they cannot disagree about a
command, its cwd, or its exit status: the keyed BashRow carries the card
resident below its summary row, and the render-site fallback row keeps it
behind its existing expand control. Rows cap at 8 lines against the
panel's 16.

Inline output in the chat row reverses this package's stated
no-inline-output convention, on the owner's explicit decision; the Agent
Note records the reversal and its bound.

Tests: TerminalBlock/ansi/clipboard unit specs, ui-conversation wiring
specs at every render site, a built-client-graph snapshot covering both
chat-row shapes, and a real-browser e2e asserting the no-wrap layout and
the page's own Clipboard API.

// @vitest-environment jsdom
// Terminal card snapshot over the BUILT client graph (the code-mode-fixture
// idiom: real bundles via AppWebEntry, keyless FixtureApiClient transport).
// Opens the fixture history session and pins the `card: 'terminal'` render
// intent at both of its conversation render sites, for both chat-row shapes:
// turn 60's `fx-bash` on the render-site fallback row (expand-gated body) and
// turn 66's `bash` on the keyed BashRow registration (resident body), plus the
// details panel's Output section. Turn 66 carries what turn 60's three plain
// lines cannot — SGR runs resolved to --dsw-* tokens, output past the chat
// cap, a nested cwd, and a non-zero exit pill.
