perf: defer document string split allocation in numeric search (#104)

Browse source 
In `src/ui/search.ts`, numeric threshold searches previously called `doc.text.split("\n")` eagerly on every open document. This commit changes `lines` to be lazily allocated only if an actual numeric search match is found, eliminating unnecessary memory allocations and loop overhead on documents that do not match.
