When parser.number_as_string(true) is set and a number exceeds uint64
range, write the raw digits to the string buffer and emit a BIGINT ('Z')
tape tag instead of returning BIGINT_ERROR. Default behavior unchanged.
Changes:
- tape_type.h: add BIGINT = 'Z'
- dom_parser_implementation.h: add _number_as_string flag
- parser.h: add number_as_string() getter/setter
- parser-inl.h: propagate flag before parse
- tape_builder.h: visit_number checks flag on BIGINT_ERROR
- tape_writer.h: add append_bigint helper
- serialization-inl.h: handle BIGINT in serialization (raw digits)
- tape.md: document big integer tape format
Builds on PR #2139 which added BIGINT_ERROR detection.
All 119 existing tests pass — default behavior unchanged.
Closes #167
