feat(dashboard): Performance page with frame times, slow frames and flame graphs

Browse Source 
The dashboard's own loop is framed too, with a scope per module update. Frame time and stacked phase charts per server, the servers' loop summary, longest frames, packet handling times, the last 50 slow frames with a nested timeline, and profiling sessions (profiling_run, GM 8) drawn as a flame graph with folded stacks to download. PerfHistory keeps it in memory and is unit tested; the layouts are tested with node. Task 96.
