Self-hosting: Write Carv compiler in Carv

[dev-dami]

Description

The ultimate goal: write the Carv compiler in Carv itself.

Why Self-Hosting?

• Proves the language is capable enough for real programs
• Dogfooding - we use what we build
• Bragging rights tbh

Prerequisites

• Module system (done in v0.2.0!)
• Package manager
• File I/O in standard library
• More robust string handling
• Possibly: generics or better type system

Roadmap

1. Write a simple lexer in Carv
2. Write the parser
3. Write the type checker
4. Write the C codegen
5. Bootstrap: compile Carv compiler with Go version, then compile itself

Milestone

This is the long-term vision. Breaking into smaller tasks as prerequisites are met.
