anchors 2

Hash-anchored read/edit/undo_last_edit tools for DeepSeek Harness (dsh). Every line gets a unique 3-char hash (A-Za-z0-9) that stays stable across edits; stale or ambiguous anchors are rejected, never fuzzy-matched. Undo persists across restarts.

Codex-style tick-rail and thinking-process fold for the DeepSeek Harness web GUI: per-turn dashes, hover preview, click-to-scroll, eager history load, and collapsed Think/tool rows.
