Hand-rebased onto current main from PR #19980; the original branch was stale
against main (~6 unrelated dashboard fixes had landed since), so applying
the PR's dist files directly would have silently reverted them.
The run-history panel in the task drawer rendered each completed run's
`metadata` field as a `<code class="hermes-kanban-run-meta">` containing
`JSON.stringify(r.metadata)` — a single unindented monoline. With
`white-space: pre-wrap` and a monospace font, a writer task's metadata
(changed_files paths, source URLs, generated-artifact details) wrapped
into a tall block of code-ish text that filled the parent run row. The
container's faint `--color-foreground 3%` background then made the whole
thing read like a crash dump even though the run completed normally.
Restyle and label, no interactivity changes:
- Wrap the meta payload in a `.hermes-kanban-run-meta-block` sub-block
with an explicit `Metadata` label (small, uppercase, muted) so the
panel reads as auxiliary detail at a glance.
- Pretty-print the JSON (`indent=2`) so the structure is scannable
instead of a wall of monoline text.
- Cap `.hermes-kanban-run-meta` at `max-height: 8.5rem; overflow: auto`
so a verbose blob scrolls inside its own pane rather than swamping
the run row.
- Sub-block uses a thin `border-left` rule and `background: transparent`
— distinct from the destructive-tinted treatment used by crashed /
timed_out / blocked / spawn_failed runs higher in the same file.
Tests: two new static-asset assertions in
`tests/plugins/test_kanban_dashboard_plugin.py` lock in the rendered
shape (the plugin ships built-only, no src/).
