Tool-result and call-bearing assistant rows now open with an inverted
mono chip naming the tool(s) (label/surface tokens swapped — black on
white in light mode, white on black in dark), multiple calls joining as
a breadcrumb (bash › write). The preview then carries the call's own
summary line: a bash-style `description`, else the target path of
path-taking tools (edit/read/write via file_path/path/filePath), falling
back to the reply text or the generic label. The redundant 'calls: …'
preview is gone — the chip says it once.
