chore(.agents): adopt the .agents/ agent-context convention (matches studio)

Add .agents/ (AGENTS.md Knowledge-map + skills/plans/handoffs/wiki) so blog matches the
cross-repo structure; human content (posts/HTML/templates) stays at repo root. Root agents.md
points to .agents/.

+## This agent
+
+**tinqs-blog** — the public Tinqs blog: static HTML built from `posts/*.md` via `build.js`. Human content
+(posts, templates, generated HTML, `img/`) lives at the **repo root**; this `.agents/` folder is the
+agent-context home. Shared identity/soul + team roster live in the hub (`../docs/.agents/`, `../docs/ai/`).
+
+## Shared context (read at session start)
+
+- `../docs/.agents/SOUL.md` — shared agent identity
+- `../docs/ai/company.md` · `../docs/ai/siblings.md` — team + repo map
+- `../docs/.agents/rules/shared-context.md` — cross-repo conventions (HTML, S3 img, deploy)
+- Root `agents.md` — blog architecture, build pipeline, post conventions (edit `.md`, never generated `.html`)

+Convention: **human content stays at repo root** (tinqs.com / Git Studio renders it); `.agents/` is
+agent-only context. Mirrors the structure in `tinqs/studio/.agents/`.
