This pull request introduces a new procedural macro package (catalog-macros) for automatic node registration in the catalog, and refactors the catalog and AI node registration codebase to leverage this macro. It also updates dependencies and simplifies catalog initialization by removing unnecessary async usage. Additionally, there are minor UI and content updates for the website.

Catalog System Improvements

• Added new package flow-like-catalog-macros with a procedural macro (register_node) to automate node registration using the inventory crate. This reduces boilerplate and simplifies adding new nodes. [1] [2]
• Updated flow-like-catalog to depend on flow-like-catalog-macros and inventory, and refactored AI node modules to use the new macro for node registration, removing manual/async registry code. [1] [2] [3] [4] [5] [6] [7] [8] [9]

Initialization and Dependency Updates

• Added packages/catalog-macros to workspace and dependencies in Cargo.toml, and updated all catalog initialization code to remove .await from get_catalog() calls, reflecting the new synchronous registration approach. [1] [2] [3] [4] [5] [6] [7]

Website and UI Fixes

• Fixed CSS selector syntax and improved styling in hero and blog header components, including updating image references and client loading for the hero section. [1] [2] [3] [4] [5] [6]
