[codex] Update JavaScript dependencies

[YurMil]

What changed

• Consolidated the Dependabot dependency updates into one branch.
• Updated the main JavaScript/tooling stack:
  • @types/node to ^25.8.0
  • express to ^5.2.1
  • @types/express to ^5.0.6
  • lucide-react to ^1.16.0
  • Vite tooling to current latest versions: vite ^8.0.13, @vitejs/plugin-react ^6.0.2, @tailwindcss/vite ^4.3.0, tailwindcss ^4.3.0, esbuild ^0.28.0, tsx ^4.22.1, typescript ~6.0.3
• Added missing React typings required by the stricter TypeScript 6 check.
• Added src/vite-env.d.ts for Vite asset/CSS module typing.
• Updated server.ts for Express 5 route compatibility and PORT env support.
• Excluded generated dist output from TypeScript checks.

Why

This replaces the separate Dependabot dependency PRs with one coherent update so peer dependencies are resolved together, especially the Vite 8 / plugin-react 6 / esbuild 0.28 set.

Validation

• npm install
• npm run lint
• npm run build
• npm test
• npm outdated --json returns {}
• npm audit --audit-level=moderate reports 0 vulnerabilities
• Production Express server verified locally with PORT=4174 NODE_ENV=production npx tsx server.ts
• Verified /api/skills response and SPA fallback route on the production server

Code Review

This pull request updates project dependencies, configures the server to use environment variables for the port, and refines TypeScript configurations. However, several dependency versions specified in package.json (such as Vite 8 and TypeScript 6) do not exist in the public registry and will cause build failures. Additionally, it is recommended to use generics in the store for better type safety instead of manual type assertions in the components.

Several dependency versions specified in this block do not exist in the public npm registry. For example, vite is currently at version 6.x, express at 5.0.x, and lucide-react at 0.4xx. Specifying non-existent versions like vite ^8.0.13, express ^5.2.1, or lucide-react ^1.16.0 will cause npm install to fail. Please revert these to the latest stable versions.

Multiple devDependencies in this section use hallucinated versions. TypeScript is currently at 5.7.x (version 6.0 does not exist), and @types/node ^25.8.0 is invalid as Node.js has not reached version 25. Additionally, esbuild ^0.28.0 and tsx ^4.22.1 are not available. These invalid versions will prevent the project from building. Please use valid, existing versions (e.g., typescript ~5.7.2, @types/node ^22.14.0).

The type assertion as Partial<Skill> | undefined is used here to satisfy a 'stricter TypeScript 6 check' mentioned in the PR description. Since TypeScript 6 is not a valid version, this assertion may be unnecessary. A more robust approach would be to properly type the nodes array in the store using generics (e.g., Node<SkillNodeData>[]) to ensure the data property is correctly typed throughout the application without requiring manual assertions.
