feat(blog): add file-based blog with dynamic slugs, MDX content and layout shell

- Introduced blog routing using Next.js App Router
- Implemented dynamic [slug] pages for blog posts
- Added MDX-based content loading via lib/posts
- Integrated shared TopBar layout with navigation
- Established clear content, lib and component separation

+/**
+ * The functions provided by this module are used to communicate certain properties
+ * about the currently running code so that Next.js can make decisions on how to handle
+ * the current execution in different rendering modes such as pre-rendering, resuming, and SSR.
+ *
+ * Today Next.js treats all code as potentially static. Certain APIs may only make sense when dynamically rendering.
+ * Traditionally this meant deopting the entire render to dynamic however with PPR we can now deopt parts
+ * of a React tree as dynamic while still keeping other parts static. There are really two different kinds of
+ * Dynamic indications.
+ *
+ * The first is simply an intention to be dynamic. unstable_noStore is an example of this where
+ * the currently executing code simply declares that the current scope is dynamic but if you use it
+ * inside unstable_cache it can still be cached. This type of indication can be removed if we ever
+ * make the default dynamic to begin with because the only way you would ever be static is inside
+ * a cache scope which this indication does not affect.
+ *
+ * The second is an indication that a dynamic data source was read. This is a stronger form of dynamic
+ * because it means that it is inappropriate to cache this at all. using a dynamic data source inside
+ * unstable_cache should error. If you want to use some dynamic data inside unstable_cache you should
+ * read that data outside the cache and pass it in as an argument to the cached function.
