kevinveenbirkenbachandClaude Opus 4.7 c02229b4be refactor(make): align targets to domain prefixes (compose-, network-, etc.)
Apply a consistent naming convention to the Make target inventory so
every target is grouped by its domain:

- compose-*  (compose-up/down/restart/stop/exec/inner-run)
- network-*  (network-dns-setup/remove, network-ipv6-disable/restore,
              network-refresh, network-trust-ca)
- security-* (security-apparmor-restore/teardown)
- diagnose-* (diagnose-network, diagnose-disk-usage)
- fix-*      (fix-chmod, fix-dockerignore)
- clean-*    (clean-cache, clean-pycache-dirs)
- install-*  (install-agent)
- meta-*     (meta-list, meta-tree, meta-mig)

Drop the stale debug-network target and reintroduce its functionality
as diagnose-network. Cascade renames through:

- Makefile (.PHONY entries, prereqs, recursive $(MAKE) calls)
- contributor docs, agent-iteration docs, role-level docs
- bundle README, environment scripts, install/lint/test wrappers
- AGENTS.md, CLAUDE.md, compose/cache.override.yml, .github/workflows

Historical entries under docs/requirements/ and changelog/ stay
untouched as audit logs.
