gitignore CLAUDE.md; redirect editing-agent guidance to AGENTS.md

CLAUDE.md was a Claude-Code-only convenience file that mostly duplicated
AGENTS.md plus a project-structure tree already covered by README's
architecture section and per-package godoc. Drop it from version
control and update AGENTS.md so its preamble no longer points at a
file that's not in the repo: editing-trond agents now start at
AGENTS.md itself, then read internal/* package docs for architecture.
