Add CLI entry point and package prompts for PyPI publishing (#10)

* feat: add CLI entry point and include prompts in package

Fixes #8

Changes:
- Add [project.scripts] entry point for uvx installation
- Include prompts/ directory in wheel package
- Force include server.py in package distribution

This enables users to install via uvx:
  uvx spec-driven-development-mcp

Package now includes:
- mcp_server/*.py (implementation files)
- prompts/*.md (3 prompt definitions)
- server.py (entry point module)
- CLI command: spec-driven-development-mcp

Tested:
- Package builds successfully
- All required files present in wheel
- Entry point loads FastMCP instance correctly

* fix: make entry point callable for console script

Address CodeRabbit review feedback by creating a callable main() function
for the console script entry point.

Changes:
- Add main() function to server.py that calls mcp.run()
- Update entry point from "server:mcp" to "server:main"
- Entry point now properly callable when installed via uvx

Fixes the TypeError that would occur when trying to invoke the
non-callable FastMCP instance directly.
