README: show feature gifs in a 2x2 grid

[FuJacob]

Summary

Adds the new autocorrect and macros gifs to the README header, and lays all four gifs out in an evenly sized 2x2 grid so they line up cleanly on GitHub.

Validation

Visual only. Rendered locally; all four gifs resolve and the grid is symmetric.

Linked issues

None.

Greptile Summary

Restructures the README demo section from two side-by-side <img> tags into an HTML <table>-based 2×2 grid, and introduces two new gif references (autocorrect.gif, macros.gif) alongside the existing slack.gif and imessage.gif.

• The table layout change is straightforward and renders correctly on GitHub for the two existing gifs.
• gifs/autocorrect.gif and gifs/macros.gif are referenced but not committed to the repository, so those two cells will show as broken images until the assets are added.

Confidence Score: 3/5

Two of the four referenced gif assets are not present in the repository, so merging as-is will display broken images in the README demo grid.

The grid layout itself is correct, but gifs/autocorrect.gif and gifs/macros.gif are absent from the repo. Visitors to the project page will see broken image placeholders in the bottom row until those files are committed.

README.md — the two new gif paths need their corresponding asset files added to the gifs/ directory.

Missing gif assets in repository

gifs/autocorrect.gif and gifs/macros.gif are referenced here but neither file exists in the repository — only gifs/slack.gif and gifs/imessage.gif are present. On GitHub, these two cells will render as broken image icons rather than the intended demos.
