Update MCP command to use scoped package name (#39)

## Summary

Updates MCP install and config to use the scoped package name
`@nicnocquee/dataqueue` instead of `dataqueue-cli`, so the MCP server
command matches the published package and works correctly when users run
the install flow.

## Important changes

- Default MCP server config now uses `npx @nicnocquee/dataqueue mcp`
instead of `npx dataqueue-cli mcp`
- Success log message after MCP install shows the new command
- Existing MCP configs written by this flow will use the scoped package
name

## Other changes

- Test expectations and fixtures updated to assert the new command in
`install-mcp-command.test.ts`

## How to test

1. From the repo root, run the MCP install (e.g. `npx
@nicnocquee/dataqueue mcp install` or the equivalent entry point).
2. Confirm the generated MCP config (e.g. in `~/.cursor/mcp.json` or the
path you use) has `args: ['@nicnocquee/dataqueue', 'mcp']` for the
dataqueue server.
3. Run `pnpm test` in `packages/dataqueue` and confirm all tests pass.
