Extra context for review: this PR adds the Codex-ready stitchflow/ skill folder directly into the catalog, while the canonical upstream project remains yshishenya/stitchflow. The same skill is already being distributed in cross-agent registries, but this PR is specifically the Codex-native packaging for users of this repo.

Quick update: StitchFlow README and packaging were improved after this PR was opened. The repo now has clearer positioning, polished install flow, richer topics/metadata, and live distribution pages (for example: https://agentskill.sh/@yshishenya/stitchflow). If useful for review, the canonical repo is still https://github.com/yshishenya/stitchflow .
