CONTRIBUTING.md structure section: top-level src/ note is stale and multimodal/ is missing from the tree #1989

Description

CONTRIBUTING.md is the entry point both README.md:282 and README.zh-CN.md:279 send contributors to, and its "Structure of the project" section now misdescribes the repository in two ways that cost a newcomer time.

1. The note claims a top-level src/ directory that no longer exists — and the same code block contradicts it.

CONTRIBUTING.md:89:

Note: The src directory is located in the top-level directory instead of the apps/{main,preload,renderer} directories because Electron Forge previously did not support Pnpm's hoisting mechanism(electron/forge#2633), requiring the src directory to be placed in the top-level directory.

Measured on main:

• ls -d src → no such directory; the desktop app's sources live in apps/ui-tars/src/{main,preload,renderer}.
• The tree a few lines above already shows them there, so the note contradicts the block it annotates.
• Upstream electron/forge#2633 ("Support pnpm"), cited as the reason, was closed on 2025-02-11 — the constraint the note documents is gone.

A contributor who trusts the note will create src/main/... at the repository root, where nothing picks it up.

2. The tree omits multimodal/, which is where the headline product of the README actually lives.

ls multimodal/ → agent-tars/, benchmark/, gui-agent/, omni-tars/, tarko/, websites/ (plus its own CONTRIBUTING.md). README.md / README.zh-CN.md open with "TARS is a Multimodal AI Agent stack … Agent TARS and UI-TARS-desktop", and Agent TARS/Tarko packages (@agent-tars/cli, @tarko/*) are all under multimodal/ — a contributor following this file cannot find them.

The packages/agent-infra listing is likewise stale: ls packages/agent-infra/ returns 11 directories while the tree lists 7 — create-new-mcp, mcp-benchmark, mcp-http-server and mcp-shared are missing. docs/ (the directory the same file's "Documentation" section tells contributors to edit) and examples/ (referenced from docs/preset.md) are missing from the tree too.

Expected behaviour

The structure section matches the repository: sources described where they are (apps/ui-tars/src), and multimodal/, docs/, examples/ plus the current agent-infra packages listed.
