Proposed Changes

This pull request aims to provide red test coverage for the #88 as the current tests are false positive.

Pull request overview

Adds stricter test assertions to ensure string variable info values are consistently serialized with surrounding quotes, addressing false-positive coverage related to #88 (inconsistent string serialization).

Changes:

• Update ZeebeVariableResolver specs to assert quoted info for string literals, static inputs, and path-resolved string values.
• Update mapping specs to assert quoted info for string-typed primitive entries and script/output mapping results.

These assertions change the expected info for string variables from unquoted (e.g. YES) to quoted (e.g. "YES"). Since this PR only updates tests (no corresponding serialization change in the resolver), this will make the existing test suite fail unless the implementation is updated in the same PR or the tests are explicitly marked as pending/red (e.g. it.skip) until the fix lands.

Suggested change

	{ name: 'staticInput', type: 'String', scope: 'ServiceTask_1', info: '"YES"' },
	{ name: 'otherStaticInput', type: 'String', scope: 'ServiceTask_1', info: '""YES""""' }
	{ name: 'staticInput', type: 'String', scope: 'ServiceTask_1', info: 'YES' },
	{ name: 'otherStaticInput', type: 'String', scope: 'ServiceTask_1', info: '""YES""' }

[Copilot]

The expected value for otherStaticInput (""YES"""") is very hard to read and easy to get wrong when adjusting tests later. Consider factoring this into a clearly named helper/constant that documents what is being asserted (e.g. raw-value-wrapped-in-quotes vs escaped FEEL literal), so the intent of the quoting behavior is unambiguous.

[Copilot]

These updated expectations require string info values to include surrounding quotes (e.g. "foo", "1"). If the resolver still derives info from the raw atomic string value, these tests will fail without a matching implementation change; consider pairing this with the serialization fix in the same PR (or marking the tests as intentionally red/pending).
