chore(release): v0.2.0

Highlights since v0.1.0:
- feat: SkillOpt-Sleep engine — nightly offline self-evolution
  (harvest -> mine -> replay -> consolidate behind a validation gate),
  with multi-objective reward, experience replay + dream rollouts,
  slow-update long-term memory, and secret redaction in cycle diagnostics.
  Shipped as the `skillopt-sleep` CLI.
- feat: cross-tool backends & plugin shells — Claude, Codex (+Desktop
  harvest), Copilot, Devin, and OpenClaw.
- feat: SearchQA split materialization + rollout fail-fast.
- fix: Windows robustness for claude/codex backends, hardened JSON
  fallback, Qwen timeout/thinking gating, Codex failure surfacing.

Packaging:
- Bump pyproject / skillopt / skillopt_sleep to 0.2.0.
- Restore skillopt_webui to the packaged wheel.
