* fix(sqlite): attribute generated-column evaluation failures to the selection
A selected virtual generated column whose expression needs a function the
read-only connection lacks (or raises an SQL error for a sampled row) was
classified by the worker's catch-all as a malformed database and projected as
an invalid_format issue on `path`.
Row reads now attribute SQLITE_ERROR from selected cells by probing each
selected virtual generated column over the sampled rows, and report a
typed capability_unavailable refusal naming the table, each failing column
with SQLite's message, and the remaining columns to select. Other causes,
including corruption, TOOBIG and NOMEM, keep their classification.
Fixes#5719

* fix(sqlite): recommend only probed-readable columns after evaluation failures
Record every per-column probe failure with its own reason, discover stored
columns outside an inventory-scope selection without decoding unrelated
malformed names, and present recovery as the structured columns selection
instead of shell-quoted command text built from database-supplied names.
