docs: add docs/ tree to AGENTS.md structure map

What

Add the docs/ directory to the ## Structure tree in AGENTS.md — it was the only top-level path missing from the map.

Why

The ## Structure block enumerates every top-level directory and even single config files (down to .releaserc), and the file header promises agents should "Reference it first." Yet it omitted the entire docs/ tree, which on main holds 18 operator-facing documentation files — BOOTSTRAP, TEMPLATING, TENANTS, node-autoscaling, oidc-kubectl, runtime-security, rwx-storage, secret-rotation, plus the 7-file disaster-recovery set under docs/dr/ (README, runbook, restore-drill, alerting, crypto-custody, openbao, velero-cnpg). docs/ is not in .templatesyncignore, so it is template-owned shared plumbing synced to every instance — exactly the kind of path the structure map should name. An agent relying on AGENTS.md as the canonical map would have missed the DR runbooks entirely.

Change

Two added entries (docs/ + docs/dr/) to the structure code-block, annotated TEMPLATE-OWNED, mirroring the existing tree style and listing the live filenames. Docs-only; no behaviour, manifest, or CI impact.

Validation

• Entries verified against the live tree (gh api .../git/trees/main?recursive=1) — every listed file exists.
• Markdown-only edit inside the existing fenced block; no build/manifest/lint path affected.

Trivial agent-file freshness fix (no behaviour change) → no separate issue filed, per the contract's trivial-fix carve-out.
