Separate architecture planning and simplify skill ownership

[mosobande]

Summary

• Add solution-architect as the implementation-ready technical architecture owner and refocus Atọna on one exact-current initiative lifecycle plan.
• Consolidate specialist contributions into receipts and one human-readable HTML plan instead of parallel plan state and reports.
• Simplify the script portfolio by removing local shadcn and Tailwind wrappers, Amoye private persistence, Brand cross-owner helpers, the legacy Slides wrapper, and inert flags while retaining safety-critical provider and lifecycle mechanisms.
• Support explicitly requested draft pull requests and merge requests in Seda while keeping new items ready by default.
• Reconcile the simplification with the current design-skill ownership model, direct routes, package metadata, and Experimental isolation.

Compatibility

This carries a major changeset. Retired commands, flags, wrappers, and private state paths are intentionally unsupported. The source repository also stops tracking machine-local skills-lock state.

🤖 Alátùńwò AI review · 📄 Diff-only

Reviewed from the pull request diff only (no surrounding files).

This PR separates technical architecture from lifecycle planning, simplifies design-skill tooling, and adds explicit draft PR/MR support.

• Blocker: whole-repository candidate snapshots no longer match any Git paths.
• Review was limited to the supplied diff because the workspace contained no repository checkout, so tests and caller behavior could not be verified directly.
