Issue	Closes #95

This PR extends env loading configuration without changing the existing bootstrap architecture.

It adds optional dotenv customization through KoalaConfig.environment.dotenv, while keeping loadEnvConfig(...) explicit and preserving Koala’s framework-managed env file order.

Pull request overview

Extends the framework’s env loading configuration by allowing users to pass through a limited set of dotenv options (via KoalaConfig.environment.dotenv and loadEnvConfig(env, options)), while preserving Koala’s framework-managed env file ordering.

Changes:

• Introduces KoalaConfig.environment.dotenv and KoalaDotenvOptions (typed from dotenv options).
• Reworks the env config loader into src/config/config-loader.ts with option support and updated/expanded tests.
• Updates internal imports/exports from @/Config to @/config, and cleans dist/ before building.
