CombatSolo portable clean engine

1. INSTALLATION
Upload and extract the archive to any target domain document root or subdirectory and open it in a browser.
The first page performs preflight. Click Install CombatSolo.
The installer auto-detects domain, filesystem root, web base path and PHP CLI; creates instance/storage; registers with DATASET; attempts to install master cron; generates the initial admin login/password; and keeps DEMO/LIVE OFF.
Save the generated credentials. The plaintext password is displayed only once and is not stored.
If automatic crontab installation is blocked by hosting, the installer shows the exact scheduler line to add manually.
The engine must obtain DATASET engine_id + token and status APPROVED before authenticated updates/profile authority become operational.
Admin login/password can be changed later in Admin Center.

Requirements: PHP 8.4+ and the required extensions shown by preflight.
Excluded from the clean archive: storage, instances, API keys, DATASET approval token, admin auth, positions, runtime and client-specific state.
