docs(manifesto): use ohmyopenagent.com (no dashes) for the project domain

The manifesto's project-context block carried the typo `oh-my-openagent.com`.
The actual canonical domain has no dashes:

- DNS: `ohmyopenagent.com` resolves (Cloudflare).
- DNS: `oh-my-openagent.com` does not resolve.
- web/wrangler.toml routes ohmyopenagent.com + ohmyopencode.org.
- web/middleware.ts redirects ohmyopencode.org -> ohmyopenagent.com.

Same fix for the legacy alias (ohmyopencode.org, also no dashes) plus an
explicit note that the legacy host 308-redirects to the canonical one so
nobody pastes the dashed form anywhere.

The project-context block had been sitting as a stale local working-tree
edit from earlier audit work and never landed on dev. Promoting it as a
clean commit so the manifesto carries the same project-context summary
the README does.
