Walkthrough

Both Query and QuerySingle methods now throw a JsonException when Options.ErrorWhenNotMatched is enabled and the JSONPath filter matches no results, instead of silently returning empty/null. Changes include new unit tests, changelog entries, and version bumps (1.1.0→1.2.0, 1.2.0→1.3.0) for the respective packages.

JSON.Query and JSON.QuerySingle exception handling

Layer / File(s)	Summary
Query throws on empty match Frends.JSON.Query/Frends.JSON.Query/Query.cs	Query materializes SelectTokens results into a List and throws JsonException when the list is empty and ErrorWhenNotMatched is true.

QuerySingle throws on null match Frends.JSON.QuerySingle/Frends.JSON.QuerySingle/QuerySingle.cs	QuerySingle stores SelectToken result in a variable, checks for null, and throws JsonException when ErrorWhenNotMatched is true.
QuerySingle tests and release notes Frends.JSON.QuerySingle/Frends.JSON.QuerySingle.UnitTests/UnitTests.cs, Frends.JSON.QuerySingle/CHANGELOG.md, Frends.JSON.QuerySingle/Frends.JSON.QuerySingle/Frends.JSON.QuerySingle.csproj	New test asserts JsonException is thrown; changelog documents the fix; package version bumped to 1.3.0.

Poem

A rabbit hops through JSON trees so deep,
When no match found, no silence to keep,
A JsonException now hops out with glee,
Two packages bumped, versions set free,
🐇 Fixed and tested, tidy as can be!
