Adds a generic ErrorContextAnalyser under
src/Analyser/ProjectZomboid/ that walks Entry[] and emits one
ErrorContextProblem per ERROR or WARNING entry with up to 20
entries of before/after context. Overlapping windows clip so no
Entry appears in two context arrays; emission caps at 500 hits
with an ErrorContextTruncatedInformation note when reached.
