v0.2.0 - Benchmark, Planner, MCP

Highlights

• Benchmark engine: 10 tasks (YAML setup/teardown/steps/verify), A/B verification, trace + screenshot per run
• Baseline v0.2: 7/10 tasks at 100%, 7 field findings (docs/baseline_v0.2.md)
• Planner: natural-language goal -> step JSON via local model
• MCP server: 6 tools for any harness
• winagent doctor: one-command environment self-check
• CI: ruff + Windows GUI smoke (real mouse/keyboard, no Ollama needed)
• IME-aware typing, session-state cleanup, tolerance-retry closed loop
