chore(agents): migrate to agents.md protocol — .agents/ wiki/plans/rules/skills

Root AGENTS.md is now a thin entry point + knowledge map; the batch-workflow
detail it duplicated already lived in .claude/skills/animation/SKILL.md.
Folded docs/ (dances registry + iclone-bridge stub), root plans/, and
devops-reports/ into .agents/wiki/ and .agents/plans/ per the per-repo .agents/
convention. Added .agents/SOUL.md, .agents/AGENTS.md, wiki/ARCHITECTURE.md,
wiki/architecture/, and wiki/master-plan.md (derived from the closed plans +
the dance registry's live ceremony-slot table). Fixed doc-path references in
exchange/GUIDE.md, the animation skill, and the iclone-bridge stub. All moves
via mv (git detected as renames) — no content deleted.

+# rules/ — always-on conventions for this repo
+
+No repo-specific rules beyond what's already always-on in root `AGENTS.md`
+(git via `tinqs push`/`tinqs pull`, stage-by-explicit-path, naming law) and the
+shared hub rules at `tinqs-ltd/docs/.agents/rules/`. Add a file here when a
+convention needs to be enforced repo-wide and doesn't fit in `AGENTS.md`'s
+thin-entry budget.
