- Lexer (Nim + Bux): resolve escape sequences (\n, \t, \r, etc) instead of keeping raw source text in token. This was the root cause of \n being double-escaped to \\n in generated C code. - Manifest parser (src_bux/manifest.bux): use bux_strlen instead of broken String_SplitCount(s, "") hack for string length; fix quote stripping. - CLI (src_bux/cli.bux): --version/--help now recognized alongside version/help. - Remove ~30+ debug Print statements from cli, parser, lexer, sema, main. - Clean up unneeded Print/PrintInt extern declarations. - _selfhost/src/: synced from src_bux/.
