Will Chen 9691c9834b Support concurrent chats (#1478)
Fixes #212 


<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Add concurrent chat support with per-chat state, chat activity UI, IPC
per-chat handling, and accompanying tests.
> 
> - **Frontend (Chat concurrency)**
> - Replace global chat atoms with per-chat maps:
`chatMessagesByIdAtom`, `isStreamingByIdAtom`, `chatErrorByIdAtom`,
`chatStreamCountByIdAtom`, `recentStreamChatIdsAtom`.
> - Update `ChatPanel`, `ChatInput`, `MessagesList`,
`DyadMarkdownParser`, and `useVersions` to read/write per-chat state.
> - Add `useSelectChat` to centralize selecting/navigating chats; wire
into `ChatList`.
> - **UI**
> - Add chat activity popover: `ChatActivityButton` and list; integrate
into `preview_panel/ActionHeader` (renamed from `PreviewHeader`) and
swap in `TitleBar`.
> - **IPC/Main**
> - Send error payloads with `chatId` on `chat:response:error`; update
`ipc_client` to route errors per chat.
> - Persist streaming partial assistant content periodically; improve
cancellation/end handling.
> - Make `FileUploadsState` per-chat (`addFileUpload({chatId,fileId},
...)`, `clear(chatId)`, `getFileUploadsForChat(chatId)`); update
handlers/processors accordingly.
> - **Testing**
> - Add e2e `concurrent_chat.spec.ts` and snapshots; extend helpers
(`snapshotMessages` timeout, chat activity helpers).
> - Fake LLM server: support `tc=` with options, optional sleep delay to
simulate concurrency.

Fake stdio MCP server

This directory contains a minimal stdio MCP server for local testing.

  • Tools:
    • calculator_add: adds two numbers. Inputs: a (number), b (number).
    • print_envs: returns all environment variables visible to the server as pretty JSON.

Requirements

  • Node 20+ (same as the repo engines)
  • Uses the repo dependency @modelcontextprotocol/sdk and zod

Launch

  • Via Node:

    node testing/fake-stdio-mcp-server.mjs
    
  • Via script (adds a stable entrypoint path):

    testing/run-fake-stdio-mcp-server.sh
    

Passing environment variables

Environment variables provided when launching (either from your shell or by the app) will be visible to the print_envs tool.

export FOO=bar
export SECRET_TOKEN=example
testing/run-fake-stdio-mcp-server.sh

Integrating with Dyad (stdio MCP)

When adding a stdio MCP server in the app, use:

  • Command: testing/run-fake-stdio-mcp-server.sh (absolute path recommended)
  • Transport: stdio
  • Args: leave empty (not required)
  • Env: optional key/values (e.g., FOO=bar)

Once connected, you should see the two tools listed:

  • calculator_add
  • print_envs
