Per-share financial-highlights parser (cef_annual.py) now reconciles
divs+gains+ROC==distributions and the full NAV chain per column for
48 of 50 shortlist funds, from three layout families (inline,
transposed, + repair rules for footnotes/split-decimals/sign-
magnitude/combined-rows). DXYZ is a correct zero-distribution result;
STEW is a documented columnar-stream exception. cef_merged.json
character column now uses actual data. 123/123 tests.
