What changes

The guidance for coding agents moves from CLAUDE.md to AGENTS.md, which other agents read too. CLAUDE.md is now one line, @AGENTS.md, which Claude Code reads as an import. CONTRIBUTING.md links the architecture rules there.

The rules were gone through one by one:

• Rule 3 held two rules. Polling stays rule 3; the event stream is rule 4, "Events say when, reads say what". It names the second reader of event payloads, the failure note on the status line from A note on the status line when something fails in any namespace #153, next to :events. Rules 4-6 become 5-7.
• Rule 3 also says a timer starts only through startTimer, and the rule on pure render says the time comes from m.now, with clockReaders listing who may read the clock. Tests already enforce both; the rules say it before a test fails.
• The list of resources urga shows and the module path are dropped: they had gone stale, and internal/ui/views.go and go.mod say them.
• "Do not copy damon" and the line from CONTRIBUTING.md about code under other licenses are one section.
• "No mention of other tools by name" now says what it meant, from the commit that added the plain-words rule: comments and commit messages name no program urga resembles, as in "the way k9s does it".
• New lines: tests that write a temporary file use tempDir(t), a PR body fills the template, commits carry no AI attribution, and only the maintainer pushes a release tag.
