Record a real same-session app GIF for the README

[YuuGR1337]

Fixes #2

Thanks for opening this. README is the right surface, but this PR does not yet satisfy #2 because it adds a placeholder comment instead of using the real v1.0.7 same-session recording that now exists.

Please replace the placeholder with the actual public GIF snippet from #2:
#2 (comment)

Direct GIF asset:
https://github.com/Snailflyer/faryo/releases/download/v1.0.7/faryo-public-redacted-same-session-handoff-walkthrough-20260528-0120.gif

Please also update the README links that still point at the older v1.0.0 launch note/install path so the proof asset and the release path both point at v1.0.7.

Once the README embeds the real redacted GIF and removes the placeholder comment, this will be in the right shape.

I rechecked the current README and this PR diff. The smallest change that would make this PR mergeable is:

1. Delete the 7-line placeholder comment.
2. Insert the real public GIF block immediately after the existing two screenshot images.
3. Update the Quickstart package URL from v1.0.0 to v1.0.8.

Suggested replacement for the placeholder area:

### Same-session walkthrough

This redacted recording shows Faryo sending short input, injecting a text handoff package, and injecting an attachment handoff package back into the same live `tmux` session:

</p>

And update Quickstart to:

curl -LO https://github.com/Snailflyer/faryo/releases/download/v1.0.8/faryo_1.0.8_all.deb
sudo dpkg -i faryo_1.0.8_all.deb

There is not yet a newer docs/launch/faryo-*.md file on the default branch, so leave the launch guide link alone for this PR unless you also add a new launch doc.
