Independent client/engine versioning with compatibility check

Split release.sh into release-client.sh and release-engine.sh for
independent release cadences. Client checks engine version on first
API call and hard-fails if engine is below MinEngineVersion.

## MODIFIED Requirements
### Requirement: Compose files for deployment
The project SHALL provide Docker Compose files for single-command deployment. Compose files SHALL use `build:` context for local development. Release notes SHALL document the versioned image tag for users pulling pre-built images.
#### Scenario: Start NVIDIA deployment
- **WHEN** an admin runs `docker compose -f compose.nvidia.yaml up -d`
- **THEN** the engine SHALL start with GPU access, bind-mount the data directory, and be reachable on the configured port
#### Scenario: Start ROCm deployment
- **WHEN** an admin runs `docker compose -f compose.rocm.yaml up -d`
- **THEN** the engine SHALL start with GPU access via ROCm device passthrough, bind-mount the data directory, and be reachable on the configured port
#### Scenario: Automatic restart
- **WHEN** the engine process crashes or the host reboots
- **THEN** Docker SHALL automatically restart the container (restart policy `unless-stopped`)
#### Scenario: Configure via environment
- **WHEN** an admin sets environment variables in the compose file (KB_MODEL, KB_API_KEY, KB_DEVICE, etc.)
- **THEN** the engine SHALL use those values
#### Scenario: Pre-built image deployment
- **WHEN** an admin wants to use a pre-built engine image without building from source
- **THEN** the engine release notes SHALL include the exact `docker pull` command with the versioned tag (e.g. `docker.dcglab.co.uk/dcg/kb/engine:engine-v2.1.0-nvidia`)
