Desktop Brand Builder (Tauri shell)

Goal

Create a branded desktop package from packages/desktop with the least user input possible. The user should usually provide only:

brandId: acme-ai
logo: /absolute/path/to/logo.png
website: https://acme.ai

website is optional. Do not ask for app name, app id, artifact name, copyright, or updater endpoints unless the user explicitly asks to override them.

This skill replaces the Electron-era brand builder that lived in the older, since-deleted Electron packages/desktop (removed in PR 9085, before this Tauri shell took over that path). The Tauri shell is the only desktop implementation now; branding hooks are src-tauri/tauri.conf.json, src-tauri/icons/, and the bootstrap/ startup UI.

Input Rules

Required fields:

• brandId: must match ^[a-z][a-z0-9-]*$
• logo: local file path; must exist; .png recommended (square, >= 1024px)

Optional overrides:

• website
• appName
• appId (Tauri bundle identifier)
• artifactPrefix
• updaterEndpoints (JSON array; empty array disables in-app updates)
• updaterPubkey (base64 public key; required when updaterEndpoints is non-empty, must match the TAURI_SIGNING_PRIVATE_KEY used to sign your updater artifacts)
• target: mac, win, linux, or all

If required input is missing, ask once:

请提供：
brandId: 例如 acme-ai，只能小写字母、数字、短横线
logo: 本地 logo 文件路径（建议 1024x1024 PNG）
website: 可选

Once the required fields are present, proceed without a confirmation step.
