test(web): pin the parallel todo plan in the assembled application

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`).

Two web sites derived their one-line summary with `todos.find(t => t.status === 'in_progress')` — the collapsed plan-strip header and the `todo_write` row — and under the old cap that `find` was total, since at most one item could match. With several active it silently dropped every active item but the first: a four-item plan with three running tasks collapsed to the name of one, and the row read `0/8 已完成 · <one task>` while seven others were in flight. The expanded list was always correct (it maps every item), which is why neither PR's tests caught it — only the collapsed header and the row lost information. The panel redesign in [#740](https://github.com/deepseek-harness/deepseek-harness/pull/740) has since replaced the collapsed header's named hint with a `<done>/<total> tasks · <n> in progress` count, which reports parallel work correctly and needs no name to truncate; the row is the one site this branch still had to fix.

 The row takes `planSummary` in `toolviews/plan-summary.ts`. It names the first active item and counts the rest, so the row reports how many tasks are running instead of implying one. Naming every active item was rejected: the row is a single line, and an unbounded join would overflow it — the count degrades predictably where a list does not. The derivation sits inside the toolviews domain rather than in `contract/`, the inter-domain face: the panel computes its own counts inline and shares nothing with the row, so a contract module would declare a sharing relationship that no longer exists.

 ## Consequences
 
-A todo list can now faithfully mirror parallel execution, and every UI renders several active markers at once: the TUI's per-status prefix needed no change, the plan strip's header counts the active items, and the row needed the derivation above. A composition that sets `allowParallelInProgress: true` no longer rejects a formerly-invalid snapshot shape; one that sets `false` keeps the old rejection, and the durable-log invariant accepts both. The model-facing description changed, which re-recorded the tool-catalog page and every snapshot sidecar carrying the todo schema. No count is recorded here: the set grows with every pinning scenario that lands, and the two point-in-time censuses this note previously carried were both stale within days. The operative rule is that a branch changing the tool description must refresh whichever sidecars landed after it branched — including the numbered `tool-schemas.<n>.expected.json` files pinning a subagent class, whose schemas the parent scenario does not cover — and `pnpm run test:snapshot:refresh` does it keylessly over the whole corpus. The web fixture's todo sample now runs two items `in_progress`, so both fixture-driven surfaces render a parallel plan — `packages/client/ui-conversation/tests/todo-panel.spec.tsx` pins the row summary and the plan strip, and the ACP `todo-write` scenario records a three-todo plan with two active — and each would fail again if its derivation returned to single-active.

That last file records `summary`, `suffix`, and the strip's header as separate fields, so folding the `+N` count back into the summary string changes the expected output even though the concatenated text would read the same.
