Used by terminal_tool, code_execution_tool, and process_registry to clean command output before returning it to the model. This prevents ANSI codes from entering the model's context — which is the root cause of models copying escape sequences into file writes. Covers the full ECMA-48 spec: CSI (including private-mode ``?`` prefix, colon-separated params, intermediate bytes), OSC (BEL and ST terminators), DCS/SOS/PM/APC string sequences, nF multi-byte escapes, Fp/Fe/Fs single-byte escapes, and 8-bit C1 control characters.

Removes ANSI/ECMA-48 escape sequences AND bare control characters, preserving only newlines and tabs (carriage returns are normalized to newlines so ``\r``-overwrite spoofing can't hide content). Use this when re-rendering conversation history or other persisted text in a terminal UI (e.g. the ``/resume`` recap): a message that arrived with embedded escapes — pasted content, gateway-origin text, or model output echoing injected tool results — must not be able to clear the screen, retitle the window, move the cursor, or restyle adjacent UI when replayed. Rich's ``Text()`` does NOT neutralize raw escape bytes, so sanitization has to happen before display.
