feat: render markdown tables in sidepanel and skill previews - #2845

@snowyukitty is attempting to deploy a commit to the esokullu's projects Team on Vercel.

A member of the Team first needs to authorize it.

thanks for the contribution @snowyukitty i think it's conflicting with an earlier commit but it can stilll merge into skills block - thanks!

@snowyukitty I'm sorry I may have accidentally erased your contribution while trying to force-push a fix to merge it. Would you like to take this #2846 instead? I won't override again, promise! :)

No harm done — I checked main and the contribution is all still there:

• src/{chrome,firefox}/src/ui/skill-markdown.js imports renderMarkdownTables from markdown-render.js
• settings.html and history.html both carry the .markdown-table-wrapper / table styling, in both browsers
• test/run.js still has both tests

There is one real problem in there, and it's mine rather than yours: those two tests are registered twice. test/run.js:13615-13651 is a byte-identical copy of 13577-13613 — I duplicated the block while putting #2845 together and didn't catch it. Node's runner happily registers both, so nothing goes red; it just runs the same assertions twice and makes the file misleading to read. Happy to send a one-file PR deleting the second copy if that's useful.

On #2846 — it's assigned to you at the moment, so say the word and I'll pick it up. One question before I would: "shorter", "top not bottom", and "same as the background but differentiated with a border" are clear, but "take a look at desktop AI agents for inspiration" could go a few ways. Do you have a specific one in mind, or is choosing the direction part of the task?
