Root AGENT.md dropped a stale paragraph; adapters that embed root
(AGENTS.md, .cursorrules, .aider.conventions.md, system-prompt.txt)
need to be regenerated to match. CLAUDE.md is project-only by design
and unchanged.
Adapters are now tracked so non-Mac hosts get full agent context after
a plain git pull. task check runs context:sync first and fails on drift
via git status --porcelain over the 5 adapter paths.
