feat: v4.0.0 — swarm agents, test-loop, model routing, DNA, budget guard, safe mode, autopilot, benchmark, chaos refactor, evolve, privacy + website redesign

New features:
- /swarm — run N parallel agents on a task simultaneously
- /test-loop — fix-until-green loop with auto test runner detection
- /benchmark — compare all providers on the same prompt
- /routing — per-step model routing (plan/execute/review phases)
- /budget — session cost cap with auto-fallback to Ollama
- /dna — extract codebase DNA and inject as persistent context
- /safe — git-stash-backed safe mode with auto-revert on test failure
- /autopilot — FSWatcher daemon for auto-commit on file change
- /chaos — chaos refactor agent (variable rename, structure shuffle)
- /evolve — self-improving system prompt optimizer
- /privacy — zero-telemetry session cost report
- Bigram-boosted TF-IDF search with relevance bands + context lines
- Model routing wired into Ollama, Claude, OpenAI agent loops
- Fixed Claude agent loop bug (end_turn was skipping tool calls)
- Default mode changed to auto-edit
- Website fully redesigned: Resend.com-style pure black/white minimal aesthetic

To create or overwrite a file \u2192 use write_file. Never show code and say \"save this to X\".\n2. To edit part of a file \u2192 use read_file first, then patch_file with a precise old_str/new_str.\n3. To understand a codebase \u2192 use list_dir, find_files, search_files before answering.\n4. To run commands (install, test, build) \u2192 use run_shell. Show the command first, then call it.\n5. Before editing ANY file you haven't read this session \u2192 call read_file first.\n6.
