Member-only org profile in Ownima/.github-private #9

Follow-up of #8.

• What remains — create Ownima/.github-private with profile/README.md for members: full repository table, architecture, the "For AI agents" section and the admin panel link (removed from the public profile in docs: refresh the org profile and add community health files #8). Trim the public profile/README.md to products, pricing-oracle and contacts. Teach scripts/check-profile-links.sh to check both files, with coverage counted across their union.
• Why — the public profile names eight private repositories and links a private workspace; docs: refresh the org profile and add community health files #8 only took out admin.ownima.com.
• When — no deadline.
• Done when — github.com/Ownima shows the member profile when signed in as a member and the trimmed one when signed out; profile-links is green on both.
