quantmodel — Show meta strategies on index.html with the same columns as individual strategies

Objective

Show meta strategies on index.html with the same columns as individual strategies.

Notes: All 12 Meta reports now use the catalog's five columns; corr/CAGR delta derive from paired payload months and missing values remain explicit.

Approach

Reuses existing report research/findings/meta-index-columns-t200.md — tables/metrics preserved verbatim via source_report pointer. Body below summarizes grounded evidence from that report and adjacent artifacts.
