[Feature]: Split Atom.Web.Server into per-application projects with central host project

[PapLabros]

Describe the solution you'd like

Currently, there is a single C# project:

Atom.Web.Server

This project:

• Contains the full server implementation

• Handles requests for multiple applications

• Defines types for all applications

• References all application-specific logic

This architecture causes:

• Poor logical separation

• Tight coupling between applications

• Excessive build times

• Full recompilation on minor changes

We need to split the server into multiple projects, one per application, and introduce a central host project that references them.

---

Goals

1. Improve logical separation per application

2. Reduce build times

3. Enable parallel compilation

4. Reduce unnecessary recompilation

5. Improve maintainability and scalability

---

Benefits

🚀 1. Reduced Build Times

Currently:

• Any change forces full recompilation of entire server project.

After split:

• Only changed project recompiles.

• Visual Studio builds projects in parallel.

• Full solution builds are significantly faster.

---

🧩 2. Proper Logical Separation

• Clear boundaries between applications

• No accidental cross-application dependencies

• Improved code ownership

---

📦 3. Better Scalability

• Easy to add new applications

• Potential future separation into independent deployments

• Easier testing and CI pipelines
