Refactors AI feedback context handling for changelog docs

Centralizes management of AI feedback context and changelog document
URIs
into a dedicated provider, improving modularity and cleanup. Updates
relevant usages to access changelog feedback context through the new
provider, removing redundant context management logic from command
files.

Simplifies resource cleanup on document close and ensures consistent
context availability for AI-related features.
