v3 Capstone: Closures + GC in the Full Pipeline

Why this module exists

This capstone proves the compiler is real at a higher bar:

• nested functions and closures
• arrays and maps
• bytecode as an artifact
• garbage collection

1) Pipeline

1. Lex
2. Parse
3. Analyze
4. Compile
5. Encode to BC2
6. Decode
7. Run in VM (with GC)

2) What to look for

• Lexical capture works (closures see outer vars)
• Indexed assignment works
• GC reclaims unreachable arrays/maps
