Add SideButton to compatibility section

[maxsv0]

SideButton provisions cloud coding agents and deploys AGENTS.md as the canonical instruction file for every workspace it creates, so an agent picks up its project instructions with no vendor-specific configuration.

• What it is: https://sidebutton.com
• How the support works: https://docs.sidebutton.com/agents-md — the workspace's instructions are written to AGENTS.md, with CLAUDE.md kept as a two-line @AGENTS.md import so Claude Code reads the same single source.
• Shipped in @sidebutton/server 1.5.2 (Apache-2.0, https://github.com/sidebutton/sidebutton).

One appended entry plus public/logos/sidebutton.svg. No other changes — the array is not reordered or reformatted. The logo is a single-path mark with the viewBox tightened to the glyph bounds, so it works with the section's mask-image treatment in both light and dark without an imageSrcLight/imageSrcDark pair. Verified locally on pnpm dev: the entry renders in the marquee and in the expanded agents grid.
