Rename skill identifiers to their Codex-specific variants and move
workflow command files to the new `-ag` and `-cc` naming scheme.
Mirror the workflow guides under both `.agents/workflows` and
`.claude/commands` so the same operational playbooks are available
through each command surface.
Add new agent skills and Claude command definitions for release
generation, VPS deployment, issue triage, PR review, discussion
review, feature implementation, and version bump workflows.
These additions document and standardize internal maintenance
operations across the release branch process and operational tooling.
