WIP: Bootstrap loop debugging

- Fixed module flattening in self-hosted compiler (Cli_Compile now unwraps module wrappers)
- buxc2 check now finds functions in module-wrapped files (token.bux: funcCount=6, Main.bux: funcCount=2)
- Added debug prints to trace lexer.bux timeout and check x segfault
- Remaining issues: lexer.bux hangs in self-hosted pipeline, check x segfaults in runtime
