Agent brand marks

Ported from the logr repo, which is where they were first assembled.

• claude-ai, codex, vscode — Simple Icons, CC0. The marks themselves stay the trademarks of their owners; they are used here only to identify which agent holds a grant, which is what trademark law calls nominative use.
• other — the Lucide bot glyph, ISC, kept for anything unrecognised. It is the fallback on purpose: an agent's name is self-asserted at registration, and drawing a company's mark beside a name nothing verified would be worse than drawing nothing.

hermes is the odd one: a 64px PNG wrapped in an SVG, so it does not scale as cleanly as the vector marks. Kept anyway — a slightly soft real mark beats a crisp generic bot.

The rest carry viewBox="-2.5 -2.5 29 29" — a 24px mark with its own padding — so they can share one tile size without per-file nudging.

claude-ai covers Claude Code and Claude Desktop alike: they are one product on two surfaces, and the chip beside the name already says which. The Anthropic wordmark that came with the original set is not here — it names the company, not the thing holding a grant.

Every mark is designed for a light ground, which is why AgentIcon sets a cream tile in both themes rather than following the surface. the Lucide bot is a mid grey that would sit poorly on the dark palette, and a light tile keeps every mark legible without per-theme variants.
