Modernize Mod Uploader 1.8.0

[lemon07r]

What changed

• Rebases the uploader modernization onto current upstream v1.7.1 and keeps
  the improved tagging UI introduced there.
• Upgrades Electron 43, Vite 8/Rolldown, TypeScript 7, React 19.2,
  Steamworks 0.12.2, electron-builder 26.15, and electron-updater 6.8.
• Standardizes installs and release version stamping on Bun, removes the npm
  lock, and validates before packaging.
• Uses vite-plugin-electron 1.x notBundle() so native Steamworks binaries
  remain external and are packaged correctly.
• Extracts testable CLI, metadata, image, error, and upload-detail modules.
• Rejects invalid Workshop IDs and missing previews, preserves update
  visibility, defaults new items public, and adds --version.
• Keeps updater metadata pointed at Lyeeedar/ModUploader.

Validation

• bun install --frozen-lockfile
• bun run release:validate
• 11 Bun tests / 20 assertions
• Vite renderer, main-process, and preload production builds
• CLI help/version/JSON-failure smoke tests
• Linux AppImage and Windows installer/portable packaging
• inspected native Steamworks payloads and packaged updater metadata

electron/main/mod-parser.ts:12

• formatModName is now duplicated here and in metadata-content.ts. Duplicating the same formatting logic makes it easy for behavior to diverge over time. Prefer re-exporting the shared helper from metadata-content.ts instead of maintaining a second copy.

export function formatModName(name: string): string {
  if (!name) return name;

  return name
    .replace(/[-_]/g, ' ')
