Create Initial Project Structure & Boilerplate

[ZFordDev]

CoffeeMD currently has a proposed file structure but no actual code or directories.
We need to scaffold the basic project layout so future work can begin.

Requirements

• Create the following directories:
  • src/core/
  • src/parsers/
  • src/renderers/
  • src/extensions/
  • reader/
  • tests/
• Add placeholder index.ts files in each folder
• Add a minimal src/index.ts that exports a dummy function (e.g., render())
• Ensure the project builds with npm run build

Notes

• No real logic yet — this is just scaffolding
• This sets the foundation for all future CoffeeMD development
