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
planSummary treated whitespace-only content as nameable, so a rejected call
whose args survive verbatim rendered a blank active clause beside a live +N.
The tool's own rule is trimmed non-empty; the row now uses it.
Also hoists the duplicated DSH_SNAPSHOT refresh flag out of the two assembled
snapshot files into their shared assembled-boot scaffolding.
The `+N` active count rides ToolRow's non-shrinking `summarySuffix` slot,
but only jsdom package suites covered it: the ACP snapshots render no web
surface and the built-boot smoke asserts no todo row. Add
`apps/web/tests/todo-row.snapshot.ts`, which boots the built client bundles
against the keyless fixture transport and records `summary`, `suffix`, and
the plan strip's header as separate fields, so folding the count back into
the summary string changes the expected output.
The three assembled-jsdom files now share `apps/web/tests/assembled-boot.ts`
instead of each carrying its own copy of the boot entry list, bundle map,
jsdom stubs, and mount call.
Also: name the policy branch in each `allowParallelInProgress` test title so
no case asserting `true` sits under a `false` describe, reword the stale cap
comment in todo-panel.spec.tsx, and record the plan strip's real header
format in the Agent Note (per-status counts, not `<done>/<total> tasks`).
