🏎️ feat: Smart Reinstall with Turborepo Caching for Better DX (#11785)

* chore: Add Turborepo support and smart reinstall script

- Updated .gitignore to include Turborepo cache directory.
- Added Turbo as a dependency in package.json and package-lock.json.
- Introduced turbo.json configuration for build tasks.
- Created smart-reinstall.js script to optimize dependency installation and package builds using Turborepo caching.

* fix: Address PR review feedback for smart reinstall

  - Fix Windows compatibility in hasTurbo() by checking for .cmd/.ps1 shims
  - Remove Unix-specific shell syntax (> /dev/null 2>&1) from cache clearing
  - Split try/catch blocks so daemon stop failure doesn't block cache clear
  - Add actionable tips in error output pointing to --force and --verbose

/**
* Smart Reinstall for LibreChat
*
* Combines cached dependency installation with Turborepo-powered builds.
*
* Dependencies (npm ci):
* Hashes package-lock.json and stores a marker in node_modules.
* Skips npm ci entirely when the lockfile hasn't changed.
*
* Package builds (Turborepo):
* Turbo hashes each package's source/config inputs, caches build
* outputs (dist/), and restores from cache when inputs match.
* Turbo v2 uses a global cache (~/.cache/turbo) that survives
* npm ci and is shared across worktrees.
*
* Usage:
* npm run smart-reinstall # Smart cached mode
* npm run smart-reinstall -- --force # Full clean reinstall, bust all caches
* npm run smart-reinstall -- --skip-client # Skip frontend (Vite) build
* npm run smart-reinstall -- --clean-cache # Wipe turbo build cache
* npm run smart-reinstall -- --verbose # Turbo verbose output
