feat(stdio): add standalone stdio entry point for Claude Desktop (#7)

* feat(smithery): add Smithery compatibility and npm publishing setup

- Refactor src/index.ts to use Smithery-compatible McpServer format with configSchema
- Add zod dependency for configuration validation
- Create smithery.yaml for TypeScript runtime deployment
- Add .npmignore to exclude development files from npm package
- Update package.json with repository metadata and enhanced keywords
- Maintain all 13 Namecheap API tools with proper Zod schemas
- Ready for both npm publish and Smithery deployment

* chore(deps): update dependencies to fix security vulnerabilities

Fixes the following vulnerabilities:
- axios: DoS attack (high) - updated to 1.13.4
- form-data: unsafe random function (critical) - updated to 4.0.5
- js-yaml: prototype pollution (moderate) - updated to 4.1.1
- qs: memory exhaustion DoS (high) - updated to 6.14.1
- @eslint/plugin-kit: ReDoS (low) - updated to 0.3.5
- body-parser: DoS (moderate) - updated to 2.2.2

Note: @modelcontextprotocol/sdk vulnerability (high) remains unfixed.
The SDK update to 1.25.3 introduces breaking TypeScript type changes
that require code modifications to resolve. This should be addressed
in a separate PR with proper type fixes.

* feat(stdio): add standalone stdio entry point for Claude Desktop

index.ts exports a Smithery factory function that never starts a server.
Claude Desktop needs a process that connects stdio transport and stays
alive. Add src/stdio.ts as the standalone entry point and update start
script to use it.

* fix(lint): remove unnecessary @ts-nocheck from stdio.ts
