Note

Low Risk
Release metadata-only change: bumps the root version and updates generated release notes; no runtime code paths are modified.

Overview
Cuts the 3.6.0 release. Updates .release-please-manifest.json to bump the root package from 3.5.8 to 3.6.0.

Regenerates CHANGELOG.md by prepending the 3.6.0 release notes (including listed breaking changes/features/fixes), resulting in a new 3.6.0 section added above an existing 3.6.0 entry.
