weichen e7fb276ee9 Skip wide sparse columns without dropping later xlsx sheets ...

Why: review of EXT-5 found a column-cap cell (common styled XFD cells) wrongly reported the 200k-cell cap and aborted every remaining worksheet; malformed sheet XML was also dropped silently, contradicting the explicit-failure contract; the legacy-office parser id was missing from the registry.

Evidence: local GOWORK=off go test ./... 29 packages pass with new regressions (wide column keeps later sheets, bad sheet XML warns, registry maps doc/xls/ppt); go vet clean; recorded as SELF on the Dev task card.

Impact: xlsxSheetBlocks returns wide/badXML signals; wide cells skip with a per-sheet warning, cell-cap truncation unchanged; builtin:legacy-office added to ParsersDescription.

Refs: review of backend 727f370; documents proposal 2026-10-06-ext-5-host-parse-document sect.2.
