Sillykjs/dsh-agents-md

Adds an Agent docs tab to the conversation view: it lists the AGENTS.md and CLAUDE.md instruction files DSH actually loads for the current session (the ~/.dsh and ~/.agents roots, plus every directory from the project root to the working directory), previews each as Markdown with per-file sizes and the 64 KiB instruction budget, edits and saves them in place after a sha256 version check, and opens the workspace folder from the path button; a saved file takes effect on the next message.
