v0.3.1

Changes

• Compile options WithStack, WithTimeout, and WithSequence for optional resource guardrails (errors D1011/D1012/D2015), matching the jsonata-js 2.2 guardrails API. Existing defaults are unchanged when these are not used.
• Sequence guardrail now covers $map, $filter, $each, wildcard (*), and descendant (**), in addition to the range operator and $append.
• Fix: $contains(str, undefined) returns undefined instead of raising T0410.
• Fix: an empty tuple-group join now returns {} instead of undefined.
• Test suite refreshed against jsonata-js v2.2.2.
• npm: gnata-js@0.3.1
