fix: add missing prepare-publish.js script for claude-code-agent v0.0.2

CRITICAL FIX: The 0.0.1 release was published without any compiled
JavaScript files because the prepare-publish.js script was missing.
This caused `npx claude-code-agent-mcp-server` to fail with
"command not found".

Changes:
- Added prepare-publish.js script to build and bundle the package
- Updated prepublishOnly script to run prepare-publish.js
- Bumped version to 0.0.2
- Updated CHANGELOG.md with fix details

The package will now correctly include the build/ directory with all
executable code when published to npm.

+
+**CRITICAL FIX:**
+
+- Added missing `prepare-publish.js` script that caused the 0.0.1 release to be published without any compiled JavaScript files
+- Updated `prepublishOnly` script to properly build and bundle the package before publishing
+- The npm package now correctly includes the `build/` directory with all executable code
+
+**Technical Details:**
+
+This fix resolves the issue where `npx claude-code-agent-mcp-server` would fail with "command not found" because the published package only contained README.md and package.json. The package now includes all necessary files for execution.
