chore(release): 0.7.0

Roll up everything since 0.6.0 into the 0.7.0 CHANGELOG and bump the version
(pyproject / __init__ / config.app_version). Rewrite the stale Unreleased Grok
entry — which described the now-deleted opencode runtime — to the shipped
reality: Grok agents on xAI's official grok CLI on a SuperGrok subscription,
plus the token auto-refresh, the self-healing CI loop, the Company Scorecard,
and the pr-reviewer / observability / usage / path-injection fixes. Also folds
the uv.lock claude-agent-sdk spec sync (>=0.2.105) merged via #216.
