chore: release 0.7.27

[hopeatina]

Summary

• bump the package version to 0.7.27
• align the OpenClaw plugin manifest version to 0.7.27
• add the 0.7.27 changelog entry for the Mission Control operator UX work shipped since 0.7.26

Test plan

• npx -y node@22 $(which npm) run typecheck
• npx -y node@22 $(which npm) run build
• npx -y node@22 ./scripts/run-targeted-test.mjs tests/http/autopilot-slice-lifecycle.test.mjs
• npx -y node@22 $(which npm) run test:hooks once locally after rebuilding better-sqlite3 for Node 22; one full-suite pass still showed a flaky failure in tests/http/autopilot-slice-lifecycle.test.mjs (Play override bypasses snake_case spawn-guard rate limits), so GitHub Actions is the merge gate for the full matrix

Rollout notes

• no runtime code changes in this PR; release metadata only
• no migrations or env changes required
