rtk 3

DSH shell executor that transparently rewrites commands through `rtk rewrite` before execution (sandbox semantics preserved).

DSH (DeepSeek Harness) plugin that auto-rewrites pwsh tool commands to their rtk equivalents before execution — cutting shell output tokens by 42-90%. Commands with no rtk equivalent pass through unchanged.

RTK (Reusable Token Kompressor) tool for DeepSeek Harness — token-optimized CLI proxy exposing read/ls/git/grep/err/test/json and more through the standard shell sandbox.
