A process inside the container could modify .devcontainer/devcontainer.json
to inject malicious mounts or initializeCommand entries that execute on the
host during the next rebuild. Bind-mounting .devcontainer/ as read-only
blocks this privilege escalation vector.
Uses startswith() for the jq filter to be precise and consistent with
other mount filters, and documents the SYS_ADMIN guard requirement.
Based on PR #12 with review feedback from @dguido addressed.
