Complete the stalled review pass: drop the unused useMemo import (rows flatten
inline), add SearchBlock to the ui-primitives README (both languages) with a
Search results section, and re-record the doc pairings. Search card behavior
and tests unchanged (313 pass).
Replace the separate '已截断 · 共 N' pill with '显示 X / 共 N 处匹配 · K 个文件'
(and '显示 X / 共 N 个路径' for glob), mirroring the read card's '显示 X / Y 行',
so the retained count and the pre-cap total read as one clause instead of two
numbers that appear to disagree.
Consume the card:'search' result view (matches grouped by file for grep, a
path list for glob) the search backend PR added. SearchBlock (ui-primitives)
draws both kinds via the kind discriminant with a per-file collapse, a
truncation pill, a height cap matching TerminalBlock, and a copy control;
search-card-model is the single resultView derivation; a keyed SearchRow
registers under grep and glob with the card resident under its summary. The
generic fallback and the details panel are search-aware. Fixture gains grep and
glob turns for the built-boot snapshot.
