* Refactor caching system to use pluggable stores

The commit modernizes the caching implementation by introducing a pluggable store interface that allows different cache backends. Key changes:

- Add Store interface for custom cache implementations
- Create default TTL-based store for backwards compatibility
- Add example LRU store for memory-bounded caching
- Support cache store configuration via options pattern
- Make cache cleanup logic implementation-specific
- Add comprehensive tests and documentation

The main goals were to:

1. Prevent unbounded memory growth through pluggable stores
2. Enable distributed caching support
3. Maintain backwards compatibility
4. Improve testability and maintainability

* Add custom cache stores docs and navigation

* Use GetOrCompute for atomic cache access

The commit introduces an atomic GetOrCompute method to the cache interface and refactors all cache implementations to use it. This prevents race conditions and duplicate computations when multiple goroutines request the same uncached key simultaneously.

The changes eliminate a time-of-check to time-of-use race condition in the original caching implementation, where separate Get/Set operations could lead to duplicate renders under high concurrency.

With GetOrCompute, the entire check-compute-store operation happens atomically while holding the lock, ensuring only one goroutine computes a value for any given key.

The API change is backwards compatible as the framework handles the GetOrCompute logic internally. Existing applications will automatically benefit from the

+Minimal example that just uses htmgo for html rendering / js support and nothing else.

+Removes automatic support for:
+
+1. live reloading
+2. tailwind recompilation
+3. page/partial route registration
+4. Single binary (since /public/ assets is required to be there), normally htmgo uses the embedded file system in other examples such as https://github.com/maddalax/htmgo/blob/master/templates/starter/assets_prod.go
