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.

- Exported searchAllSheets from src/ui/search.ts
- Added comprehensive unit tests in src/ui/search.test.ts testing full-text and numeric threshold searches
Both were self-contained enough to live in their own modules —
src/ui/search.ts (Ctrl+F overlay, text and result-value queries) and
src/ui/export.ts (render the sheet + results to a PNG, clipboard or
file). Trims main.ts by about 150 lines.
Also fixes a real bug while it's in there: the PNG export's clipboard
fallback did btoa(String.fromCharCode(...bytes)), which blows the
call stack on large sheets (spreading a big array as call arguments).
Chunks the conversion in 0x8000-byte pieces instead.
