v1.16.0: reliable jumping and rendering

Signed by Mozilla for Firefox 140 or later, plus an unpacked build for Chrome, Edge and Brave.

Firefox: click markdown-pr-sentence-comments-1.16.0.xpi below and allow github.com to install the add-on.

Chrome, Edge, Brave: download markdown-pr-sentence-comments-chrome-1.16.0.zip, unzip it to a folder you keep, open chrome://extensions, switch on Developer mode, and click Load unpacked. For an update, replace the folder contents and click the reload icon.

Fixed in this version:

• The jump to the proposal works. The render sweep scrolls the page to force GitHub to mount every file and then restores its own position, which silently undid the jump and left you at the first file. It now restores only when nothing else moved the reader.
• Rendering no longer loops. Instead of re-running startup until the files appear, it waits in the background for GitHub's file list and renders once.
• Clicking a row lands in the right place. A jump waits until the block exists, falls back to the nearest block after the line, and corrects itself until the target stops moving.
