refactor: console improvements — auto-discovery, centralized bootstrap, per-command help

- ConsoleApplication.discoverCommands() scans lib/Console/Commands/ automatically;
  adding a new command no longer requires editing bin/console
- Command base class provides bootstrapApp(), bootstrapModuleApp(), requireBinScript()
  and projectRoot() helpers — eliminates fragile 4-level relative require_once paths
- Per-command --help support via optional usage() method on Command
- Docker-compose scheduler updated to use bin/console scheduler:run
- Old bin scripts now emit deprecation hint to stderr when called directly
