## Summary
Makes the runs list customizable. A new **Display** control lets you
show, hide, and reorder columns, and add **smart columns** that pull a
single value out of a run's payload, metadata, or output by JSON path
(e.g. `$.failed`, `$.order.total`). Column choices live in the page URL,
so a view can be bookmarked or shared. Applies to the global runs list
and every per-task / scheduled / agent / webhook / error list, which all
share one table.
ID, Task, and Status can be reordered but not hidden. Smart columns are
display-only (no sort or filter, which would defeat the ClickHouse sort
key and cursor).
## How it works
Columns come from a shared registry; the Postgres `select` is derived
from the visible columns, so a run's large payload/output are only
hydrated when a smart column actually references them. All JSON parsing
for smart columns happens client-side, respecting the packet content
type, parsed once per source per row. Offloaded (too-large) values and
paths that aren't present render distinct placeholders rather than
fetching per row. The live poll carries the same sources so smart-column
values update in place.
Scalar columns stay always-selected for now: the shared list presenter
has a fixed output shape consumed by several routes and the live poll,
and narrowing individual scalar fields would add no real query cost
benefit on a single-row read. The select derivation is already
column-driven, so tightening this later is a one-line change.
