fix: read version dynamically from package.json

[bigknoxy]

Problem

The CLI version was hardcoded as '0.1.0' in src/index.ts. When package.json was bumped to 0.1.2, the CLI still reported 0.1.0.

Solution

Read version dynamically from package.json at runtime using createRequire from node:module.

Changes

• Import createRequire from node:module
• Load package.json using require() (ESM-compatible approach)
• Use pkg.version instead of hardcoded string

Testing

$ npm run build
$ node dist/index.js --version
0.1.2
