test(app): remove wheel listener race

Give generic session schedule fixtures an explicit empty heartbeat activity result and declare both activity dependencies in the git-watch fixture. This preserves strict stubs while covering the workspace descriptor inputs introduced by heartbeat projection.

+- **Heartbeat** — Ephemeral cron prompt sent back into the same agent/conversation. Agent surfaces expose create, update cron, and delete only. Use for reminders and babysitting where status should return inline. The agent's **Heartbeats track** lists the ones still on a cadence for that agent on that host; opening a row goes to it on Schedules (`/schedules?serverId=…&scheduleId=…`, keyed by both because schedule ids are host-local). Paused, completed, and expired heartbeats stay on Schedules and leave the track. A host without `heartbeatWorkspaceActivity` still runs the prompts but does not report them as workspace activity, so the track links to host settings instead of contradicting the workspace status.
 - **Mode** — Provider-specific operational mode (plan, default, full-access, …). UI: icon-only. Code: `modeId` in `AgentSessionConfig` (`packages/protocol/src/messages.ts:257`).
 - **Attachment** — External or local context bound to an agent prompt: forge issue/change request, review context, uploaded file, text, or image. UI: "Attach issue or PR/MR". Code: `AgentAttachment` (`packages/protocol/src/messages.ts:782`).

 - **Attachment tray** — The selected-attachments row inside the composer input, above the text input. Code: `renderAttachmentTray` (`packages/app/src/composer/index.tsx`). Forbidden: "Attachment bar".
 - **Fork** — Starting a NEW agent session seeded with a copy of another session's curated chat history. The history rides along as a `chat_history` composer attachment on a draft; the fork does **not** resume or branch the provider-side session, and the source session keeps running untouched. Two targets, one surface, one RPC (`agent.fork_context`, gated on the `agentForkContext` host feature). UI: the fork menu lives in the assistant turn footer and offers "Fork in a new tab" / "Fork in a new workspace". On a **completed** turn it sits beside the copy button and pins a boundary to that turn, so the fork stops where the turn ended. On the **in-flight** turn it sits beside the progress loader and elapsed timer, and omits the boundary entirely — `selectForkContextRows` projects the whole timeline when no boundary is given, so the fork captures everything **up to now**, including the response still streaming. That omission is what makes mid-run forking work; pinning a boundary there would silently drop the live response. Forbidden on provider-subagent (read-only) panes. Code: `useForkAgent` (`packages/app/src/hooks/use-fork-agent.ts`), `selectForkContextRows` (`packages/server/src/server/agent/activity-curator.ts`). Don't confuse with: git fork (unrelated; Paseo has no such concept), **Worktree** (filesystem isolation, not history copying).
