refactor(Common): Simplify IPC module documentation and remove Effect constructors

Condense the IPC module doc comment from a verbose block explanation to a concise one-line summary. Remove inline BEM-style section comments that duplicated the module names.

Drop the `EstablishHostConnection` and `ProxyCallToSideCar` effect constructor modules as the IPC abstraction is being streamlined—only `SendNotificationToSideCar` and `SendRequestToSideCar` remain for active sidecar communication patterns.

The core IPC contract (`IPCProvider`), channel registry, and Sky event table stay intact.

-//! This module defines the abstract contract for the Inter-Process

-//! related Data Transfer Objects (DTOs), and the `ActionEffect` constructors
-//! for all IPC operations.
+//! IPC: channel registry, Sky event table, provider trait, DTOs, effect
+//! constructors.
