Adds a step-by-step article for issue #36 showing how to run Omni Engineer inside Daytona with a Dev Container, plus a parallel Claude Engineer Dev Container workflow.

Included:

• Article: articles/20260512_omni_claude_engineers_inside_daytona.md
• Original SVG diagram asset
• Dev Container definition page
• First-time author profile
• Links to upstream Dev Container PRs:
  • Omni Engineer: https://github.com/Doriandarko/omni-engineer/pull/29
  • Claude Engineer: https://github.com/Doriandarko/claude-engineer/pull/253

Validation performed:

• npx markdownlint articles/20260512_omni_claude_engineers_inside_daytona.md definitions/20260512_definition_dev_container.md authors/chidubem-nwagbo.md
• git diff --cached --check before commit
• For both upstream Dev Container PRs: JSON validation, whitespace check, Python compile check, and fresh venv pip install -r requirements.txt

Note: full npm run lint:md currently reports pre-existing lint issues in older repository files unrelated to this PR, so I validated the new/changed Markdown files directly.

Closes #36 /claim #36
