Lands the end-to-end CoreSync demo (frost-influx-grafana.flow.json) along with the supporting normalizer/identity/interpolation/reducer work, plus a targeted fix for the under-compression bug surfaced by the FROST demo. Under-compression fix (PointReducer): - New burstWindowMs option (default 0, opt-in). When two samples arrive within burstWindowMs of each other, the second is treated as the same wall-clock observation: previous is replaced, slope analysis is skipped. - Without this guard, sub-millisecond bursts (rotatingMachine emits twice per pressure-injection cycle, ~1 ms apart) produced near-vertical apparent slopes that tripped angle-change on every tick — driving cog/efficiency/SEC streams to ~0.6% reduction (i.e. no compression). - With burstWindowMs: 10 in the demo flow, the same streams now compress at 78-93% (verified end-to-end in InfluxDB over a 3-min window). - Editor HTML exposes the new "Burst dt" field with explanatory tooltip. Regression test (test/basic/coresync.basic.test.js): - New "burstWindowMs collapses sub-tick sample bursts into a single observation" test reproduces the exact burst pattern from the demo and asserts before/after behaviour. - Existing 14 tests continue to pass.
