feat: create public wcmchenry3-stack/profile repo for org homepage

[wcmchenry3-stack]

Context

When the .github repo goes private, github.com/wcmchenry3-stack will show a blank org homepage unless a public profile repo exists. GitHub serves wcmchenry3-stack/profile/README.md as the org's public-facing profile page.

This issue MUST be completed before issue #88 (make .github private).

Implementation

1. Create wcmchenry3-stack/profile repo

• Visibility: public (required for GitHub to serve the profile)
• Initialize with a README
• Add .github/ and profile/ directories per GitHub's spec
• The profile README lives at profile/README.md

2. Create profile/README.md

Content should include:

• Org name and brief description (small private stack org)
• What the org builds (overview of active projects)
• Links to any public-facing apps (if deployed)
• Tech stack overview (brief)
• Note that most repos are private
• Contact / contribution note (reference CONTRIBUTING.md)

Keep it concise — this is a public-facing page.

3. Verify org homepage

After creating and pushing the profile repo:

• Visit https://github.com/wcmchenry3-stack in a browser
• Confirm the org homepage shows the profile/README.md content
• Confirm it renders correctly (no broken markdown, no broken links)

Acceptance Criteria

• wcmchenry3-stack/profile repo created as a public repo
• profile/README.md exists in the repo with org description content
• https://github.com/wcmchenry3-stack displays the profile README content
• Repo has its own CODEOWNERS, LICENSE, and basic .github/ config (or inherits from org if already public)
• Profile README passes markdownlint

Dependencies

None — can be worked in parallel with Phase 2 issues.
Must complete before issue #88 (make .github private).
