Service READMEs now cover only what the service is and how to deploy it.
Known issues, log noise and troubleshooting move to docs/<service>/, named
after the service directory, so editing them never redeploys the service.
Drop alloy's validate workflow, which never ran from a subdirectory.
A service README now describes only its own service: no links to other
services or to the root, and no restating of the shared conventions that
the root README and CLAUDE.md already carry. Each service is a separate
Coolify app on a <service>/** watch path, so a cross-link made editing one
service redeploy another. The rule is recorded at the root; the alloy
compose comment now points at a heading that exists.
