Lexer

Tokenizer, quote handling, variable expansion & tilde expansion.

Tokenizer, quote handling, variable expansion & tilde expansion.

The lexer transforms the input into a linked list of t_token nodes.
Each token carries a type, a value string and a quote context.
After tokenization, expand_all_tokens() replaces $VARIABLE references in place (while respecting quote rules) and expand_tilde() handles ~ expansion.
