Tom Boucher 616b387f12 perf(#320): hoist By-Phase state table regex to module scope (#403) ...

Static regex literal `byPhaseTablePattern` was recompiled on every call to `updatePerformanceMetricsSection`; hoisted to module scope (compiled once; stateless /i used with .match → safe to share across calls). `phaseRowPattern` uses dynamic interpolation and stays in-function. `Fixes #320`.
