fix(cli): resolve alias correctly for Vite projects using tsconfig.app.json

[Manoj-M-S]

Summary

Fixes #11044

The tsconfig-paths library's loadConfig only reads the root tsconfig.json. In modern Vite projects scaffolded by create-vite, the root tsconfig.json contains only references (e.g., { "references": [{"path": "./tsconfig.app.json"}] }) while the actual paths config lives in tsconfig.app.json.

Since loadConfig doesn't follow references, it returns empty paths, causing the CLI to treat @/components as a literal filesystem path — creating a physical @/ directory instead of resolving to src/components/.

Fix

When loadConfig returns a successful result but with no paths, fall back to manually reading tsconfig.json, tsconfig.web.json, and tsconfig.app.json to find compilerOptions.paths. This covers the standard Vite split-config pattern without changing behavior for projects where loadConfig already works.
