The skill name spec requires lowercase letters, numbers, and hyphens
only. Change `name` from "Migrate from OpenAI App" to `migrate-oai-app`.
Companion to #443, which does the same for the `create-mcp-app` skill.

Adds a new skill (`plugins/mcp-apps/skills/migrate-oai-app/SKILL.md`)
that guides developers through migrating OpenAI Apps SDK applications
to the MCP Apps SDK. Includes API mapping tables, CSP configuration
guidance, and a "Before Finishing" checklist.
Also fixes the `registerAppResource()` JSDoc example in `src/server/index.ts`
to show CSP configuration in the correct location (on the content item,
not the resource config).
