MCP manifest references a non-existent future schema version

- skills/smithery-manifest/SKILL.md:31-36
The manifest hardcodes a $schema URL dated 2025-12-11, which is unlikely to exist yet. Schema validators and registry tooling may fail to load or validate against this URL, causing submission or tooling breakage.
Recommendation
Update $schema to a currently published MCP Registry schema URL from the official docs (for example, the latest stable server.schema.json) or omit $schema until a valid one is confirmed. Add a generation-time check in the smithery-manifest skill to verify the schema URL returns 200 before writing it.
