Clicking a watch-state row now shows HOW the verdict evolved, not just the
latest flags:
- setup score across the session vs the 60% gate (SVG line)
- relative volume vs its 2.5x floor
- per-criterion pass/fail lanes over the whole session (the variance of
each logical step at a glance)
- each criterion's latest reason in words (rvol 4.9 (min 2.5), gap 80.9%,
price vs breakout ...) instead of bare pass/fail marks
Backend: query_symbol_criteria gains history[] (server-side strided to
~240 samples) + detail[]. The generic LIKE scan took 12s/click over weeks
of criteria rows; now a partial expression index on the extracted symbol
(idx_events_criteria_symbol, built at boot) + 24h window + SQL-side
stride = <1s. Latest-verdict fallback keeps stale symbols and historical
views working (covered by existing projection tests).
