v1.2.3

Materialize agents & skills into the project by default. ccsk init now copies the 12 agents + 16 skills into .claude/{agents,skills} so the kit is self-contained and visible per-project — no plugin install or trust dialog needed. Skills become /ccsk-<name> commands, agents stay bare (planner, code-reviewer); a namespace transform rewrites the plugin ccsk: references so cross-refs and subagent delegation resolve.

Use ccsk init --plugin for the legacy plugin delivery (colon commands /ccsk:plan, nothing copied). The post-install summary now counts what actually landed, and ccsk update refreshes a materialized project in place.
