Note

Overview
Release Please bumps ldcli from 3.12.0 to 3.13.0 in package.json, .release-please-manifest.json, and the PROVENANCE.md verification example, and adds the 3.13.0 section to CHANGELOG.md.

That release note documents what ships in this tag: a large prompt sync surface (workspaces, sync orchestration, manifests/sync.lock, attachments, scriptable commands, and related fixes), dev server improvements (local flag overrides, FDv2 client protocol, localhost binding, request/debug limits), ldcli aws-devops-agent setup, and agent Simple English hooks.
