feat(desktop): isolate dev URL scheme

[src-opn]

Summary

• add an Electron Builder dev config for an OpenWork-Dev app variant
• register openwork-dev:// for dev builds while keeping openwork:// on packaged production builds
• make pnpm dev package and launch the dev Electron bundle by default, with OPENWORK_ELECTRON_DEV_BUNDLE=0 as the raw Electron opt-out

Verification

• node --check apps/desktop/scripts/electron-dev.mjs
• node --check apps/desktop/electron/main.mjs
• pnpm -C apps/desktop exec node -e "const fs=require('node:fs'); const YAML=require('yaml'); YAML.parse(fs.readFileSync('electron-builder.dev.yml','utf8'));"
• git diff --check

Known issue

• pnpm -C apps/desktop typecheck:electron still fails on existing Electron typing issues in browser-mcp.mjs, browser-native-tools.mjs, and menu typing in main.mjs. These are unrelated to this change.

Demo

• No video/screenshot captured; change was verified with syntax/config checks only.
