Module lexer 

A deliberately tiny, hand-written tokenizer for fslite-command’s line grammar. It is not a shell: there is no expansion of any kind (globs, $VAR, ~, command substitution) and no shell metacharacter (|, ;, &, <, >, backtick, $() is ever treated as literal text when it appears unquoted — it is rejected outright, so a user who pastes a real shell command gets a clear error instead of a confusing partial parse.
