fix: align installer dependencies with root package versions for ESM compatibility (#420)

Downgrade chalk, inquirer, and ora in tools/installer to CommonJS-compatible versions:
- chalk: ^5.4.1 -> ^4.1.2
- inquirer: ^12.6.3 -> ^8.2.6
- ora: ^8.2.0 -> ^5.4.1

Resolves 'is not a function' errors caused by ESM/CommonJS incompatibility.
