Description

Add a set of tools that will let Dexter interact with the local file system and read, write, and edit files. The tools should request permissions from the user like Claude Code does and then persist the permissions across sesions.

Contributor guide

Research direction
Investigate the existing tool system in Dexter, understand how permission prompts are implemented (similar to Claude Code), and then add ReadFile, WriteFile, and EditFile tools following the same pattern. Ensure session persistence for permissions.
