Every keystroke in the search box scanned, lowercased, and split the
full text of every history entry, and the preview pane laid out the
entire selection with WrapAnywhere. A single 1.6MB paste (or a large
file selection) turned that into hundreds of megabytes of work on the
shell thread and stalled the render thread — freezing the whole
desktop.
Cap each entry once as it enters the display, so searching, previewing,
and rendering all work on a bounded prefix. Pasting reads the full entry
back from history by index, so nothing is actually lost. The cut lands
on a line break, keeping a file:// URI from truncating into a bogus path.

Clipboard history selections passed the full selected text as a process argument to omarchy-clipboard-paste-text. Large entries can exceed Linux's per-argument exec limit, so the helper never starts reliably for big copied blocks.
Pass the original history index instead and have the helper read that entry from clipboard-history.json before wl-copy and Shift+Insert. Also focus the first row when opening the manager, keep filtered rows mapped to their original history indexes, and drop whitespace-only text entries.
