Closes #533.

Stdio MCP servers now accept --pkg-version on CLI create/update, show the stored pin in get, and register the package argument with the requested version for npx and uvx. The gateway slug stays unchanged, preserving tool names. Existing package pins are replaced, and registration does not mutate the stored argument list.

Validation: 31 focused Vitest tests; shared build; CLI TypeScript check.
