Subject: [PATCH] perf: typing in the chat input no longer freezes after
 pasting large text (#33729)

Converting 16,000 pasted lines to Markdown now takes 74 ms instead of 8.6 seconds, with byte-identical output. The converter got about 4x slower each time the text doubled, so every keystroke in the chat input after a large paste took seconds; its latest release fixes that and this is a plain version bump.

| Pasted lines | Before | After |
|---|---|---|
| 16,000 | 8,634 ms | 74 ms |
| 8,000 | 2,232 ms | 39 ms |
| 4,000 | 575 ms | 17 ms |
| 1,000 | 31 ms | 16 ms |

Related to #12087.
