Parse payloads from Text slices

Literal and token parsers still converted through String or built Text
one character at a time. Capture chunks from the Text input directly
for identifiers, numbers, string fragments, format specs, quote runs,
and escape digits.

This keeps source spans stable and makes the affected numeric
diagnostics use more precise decimal and hexadecimal digit labels,
while reducing intermediate allocation before AST construction. Update the
kinds and types bench readers to keep benchmark sources in Text too.
