creatixchu e4ca03cb85 fix(web): surface max-tokens turn ends as a localized truncation notice
A turn the provider ends at its per-request output cap previously produced
no visible sign in the Web chat flow: only error-kind turn/end events built
a conversation node, so the truncated answer read as a normal completion.

Add a turn-max-tokens conversation node Definition over the durable
turn/end event, a warning-styled localized notice row distinct from
turn-error, a fixture max-tokens sample turn, and an assembled keyless
snapshot pinning the dot state, title, and hint.

Closes #1522

// @vitest-environment jsdom
// Assembled todo snapshot: boots the real built `packages/client/*/lib/
// client.js` bundles through AppWebEntry's ModuleLoader path against the
// keyless FixtureApiClient transport, opens the fixture session, and pins the
// two surfaces the fixture's parallel plan (turn 74, two items `in_progress`)
// reaches — the `todo_write` tool row and the dock's plan strip.
//
// The row is pinned as three separate fields on purpose. `summary=` is the
// ellipsized text and `suffix=` is ToolRow's non-shrinking `summarySuffix`
// slot, so a regression that folds the `+N` count back into the summary string
// changes this file even though the concatenated text would read the same; the
// jsdom package suites bench over src and cannot see the bundled registration.
