`<{name}>` previously wrapped a list-typed capture's whole
comma-joined string in one code block: `{|| id , name }`. Harbour's
std.ch expects per-element wrapping so `{ <{v}> }` against
`LIST id, name` yields `{ {|| id }, {|| name } }` — an array of
column blocks the call site can evaluate per row.
applyResult now consults the marker table for blockify the same way
it already does for smart-stringify, splits the captured list on
top-level commas, and emits one `{|| expr }` per element.
Prereq for the upcoming LIST / DISPLAY rules; no user-visible
behavior change for the rules already in std.ch (their `<{for}>` /
`<{while}>` markers are scalar).
