StatePathFilter class

Utility for filtering state data by specific field paths.

This class provides functionality to extract only specified paths from nested Map structures using dot notation (e.g., "user.profile.email").

Path Notation:

• Dot notation: "user.profile.email" extracts data["user"]["profile"]["email"]
• Top-level fields: "name" extracts data["name"]

Behavior:

• Missing paths are silently ignored
• Nested structure is preserved (e.g., "profile.email" keeps the profile map)
• Returns a new Map containing only the specified paths
