Retroactive design + plan documentation for Phase B.2 (PvP combat
detection plus six admin verb-dispatch insight classes), reconstructed
from chat history and git log. Mirrors the shape of the existing
Phase B.1 docs. Plan is as-built with checkboxes pre-checked and
commit SHAs referenced inline; Deviations section captures the
90c85a0 brace-fix interlude.
Captures the decision to forgo custom Analyser subclasses (the framework's
PatternAnalyser already handles multi-line entry text via Entry::__toString),
the five Insight components under src/Analysis/ProjectZomboid/, the new
DebugServerPattern::EXCEPTION constant for header+stack-body capture, the
PatternAnalyser configuration that ServerLog::getDefaultAnalyser will return,
the per-class coalescing semantics, and the test plan that drives the existing
synthetic debug-server-minimal.txt fixture end-to-end.
