feat: Export everything under a single module name

[webJose]

This PR repeats all exports from the @svelte-router/core/kernel sub-module in the main module, @svelte-router/core. This is to allow externalizing the entire library in one go when doing micro-frontends.

From now on, don't consume the submodule @svelte-router/core/kernel.

Pull request overview

This PR consolidates all exports from the @svelte-router/core/kernel sub-module into the main @svelte-router/core module to simplify library consumption in micro-frontend scenarios where the entire library needs to be externalized. The sub-module is deprecated as of v1.0.4 and will be removed in v2.0.

Key changes:

• Re-exported all kernel module functions and classes through the main module index
• Updated all documentation and code examples to import from @svelte-router/core instead of @svelte-router/core/kernel
• Added deprecation warnings in API documentation about the kernel sub-module
