build: rebuild .tox binaries against v2.1.0 sources

Bakes the v2.1.0 release into both .tox files:
- CLI tox: API_VERSION = "2.1.0", patch session lifecycle fixes,
  td_python_help actionable errors, WS URI redaction, security
  audit fixes (.mcp.json template, npm hardening, install.sh path).
- Standalone tox: chat UI rework (quiet-mode toggle replaces font
  toggle, smaller fonts, contextual ASCII flourishes on turn-end),
  live model-tier propagation in runtime.py, the same patch
  session + recovery hint Python-side fixes.

Mirrors the v2.0.0 release pattern: 5a867c2 → b0c306f, ce911e5
→ this commit.
