gate: add kunchenguid/no-mistakes for all Nix harnesses

- home.nix: add home.activation.noMistakes (declarative install to
  ~/.no-mistakes/bin + daemon via launchd, global config fallback
  agent: [pi, opencode, grok, claude, codex] covering every harness
  declared in Nix; fix shadowing of jonathanong npm no-mistakes)
- ~/.no-mistakes/config.yaml: switched from auto to ordered fallback,
  pi first (firstmate crewmates), then opencode/grok
- home/.pi/agent/*, home/.grok/config.toml, home/.config/opencode2:
  align to oMLX/qwen3.6-35b local model (was mixed Talos/genesis)
- rebuild.sh: ensure grok-build upgrade and OpenCode 1.x install on
  rebuild (stable CLI for free-tier, opencode2 beta is 426 there)
- dotfiles repo: no-mistakes init (gate at
  ~/.no-mistakes/repos/916cb6ded81b.git, remote no-mistakes)
