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.

+# SOUL.md — animation repo identity
+
+Inherits the shared identity, values, and confidentiality rules from the hub:
+`tinqs-ltd/docs/.agents/SOUL.md`. Read that first if this is your first session
+on any Tinqs repo.
+
+## What this repo is
+
+The animation-pipeline hub and Mac↔PC bridge for Ariki. iClone 8 + Video Mocap
+run on Jeremy's Windows PC; Blender 5, the retarget tools, and `ariki-game` live
+on both machines. This repo carries the skills, tools, and files-in-flight that
+turn PC-side motion capture (iClone renders, video mocap) into game-ready
+Quaternius-rig GLB clips consumed by `ariki-game`.
+
+## Scope
+
+- **In scope:** FBX→GLB retargeting (Blender headless), loop QC and loop-fixing,
+  dance/clip naming and the registry, boat/prop export, the exchange-folder
+  bridge protocol, and the skills that encode iClone/mocap operator knowledge.
+- **Out of scope:** game-side rendering, ClipCatalog code, dance ceremony
+  design (owned by `ariki-game`) — this repo only produces and ships the assets.
+
+## Confidentiality
+
+Same as the hub: this repo is private/internal. No special classified material
+lives here (Cosmos-related confidentiality does not apply to animation tooling).
