feat: parity milestone — add linux-to-sync, mark v1.0.0

Every service from ubuntu-post-install-24.04-crowdsec.sh is now a module.
35 services across 8 categories; setup.sh is the primary install path.

- services/linux-to-sync.sh (extras): clone private repo via SSH or PAT
- setup.sh: is_installed case for linux-to-sync (~/.git marker)
- MODULAR.md: migration table updated to show full inventory
- VERSION: 0.9.11 → 1.0.0 (parity achieved)

 ## Migration status
 
-This is an incremental migration. The big `ubuntu-post-install-*-crowdsec.sh`
-script remains the current "install everything" entry point until the modules
-reach parity, at which point it is retired (like the `original` and
-`-no-keycloak` tiers, which stay frozen as the evolution record).
+Migration is complete. `setup.sh` + `services/` now cover every service
+from `ubuntu-post-install-*-crowdsec.sh` plus several extras. The monolith
+is retained as a frozen evolution record.
