Builder Pattern Configuration With Fluent Api Chaining

via “fluent serverbuilder configuration interface”

** (PHP) - Core PHP implementation for the Model Context Protocol (MCP) server

Unique: Implements fluent builder pattern for server configuration, enabling readable method chaining for setting up transports, DI containers, caching, sessions, and element discovery. The builder accumulates configuration and creates a fully-initialized Server instance, making configuration self-documenting and easy to modify.

vs others: More readable than array-based configuration because method chaining makes configuration intent explicit and enables IDE autocomplete, reducing configuration errors and improving maintainability.
