- Added cluster_master_weight config option (default: 'auto')
- Implemented weight precedence: command line > config file > default 'auto'
- 'auto' mode enables automatic weight adjustment (100->0 on first client, 0->100 when all disconnect)
- Explicit numeric weights disable automatic adjustment
- Updated sample config file with cluster_master_weight setting
- Enhanced command line parsing to accept 'auto' or numeric values
- Improved startup messages to indicate weight source and behavior

- Added weight_explicit flag to track if --weight was specified on command line
- Automatic weight changes (100->0 on first client, 0->100 on last disconnect) only apply when weight is not explicitly set
- When --weight is specified, master maintains the explicit weight regardless of client connections
- Updated command line help and startup messages to clarify the behavior
- This allows administrators to override automatic weight management when needed

- Modified API to aggregate workers per node instead of showing each worker separately
- Each cluster node now appears as a single row with summarized worker information
- Workers column shows count and types: '2 workers - Analysis (CUDA), Training (ROCm)'

- Updated API documentation to reflect new response format with workers_summary field

- Detect running local worker processes on cluster master using psutil

Implement secure websockets for cluster master and client with auto-generated self-signed certificates

Show all defaults in /admin/config if not set in database, hide configs set by config file/CLI/env, add redis config

Modify /admin/config to show only database-set configurations, excluding database and network configs

- Modified analysis page to only show stats sidebar for admin users
- Enhanced /api/stats endpoint to include cluster information for admins
- Added GPU backend detection summary to stats
- Updated JavaScript to display comprehensive system and cluster stats
- Stats now show local resource usage and cluster status for administrators

Note: Full job-specific worker stats (showing resources from the machine executing each specific job) would require additional development to track job-to-worker mappings and implement worker resource reporting.

- Added --weight parameter to client connections (default: 100)
- Modified cluster master to prioritize GPU-enabled clients for job distribution
- GPU clients always get precedence over CPU-only clients
- When no GPU workers have required model, GPU clients still preferred for model distribution
- Client weights are combined with process weights for load balancing
- Higher weight = more jobs assigned to that client

Job distribution priority:
1. GPU clients with required model already loaded
2. CPU clients with required model already loaded
3. GPU clients (model will be sent)
4. CPU clients (model will be sent)

Within each category, clients are selected based on combined weight.

- Added --no-gpu command line flag
- When --no-gpu is specified or no GPUs are detected, local worker processes are not started
- This allows running vidai as a cluster master without local GPU processing
- Useful for dedicated cluster master nodes that only manage remote clients

- Add GPU detection utility functions in compat.py
- Modify vidai.py to detect GPUs at startup and configure backends
- Update cluster_client.py to detect GPUs and send capabilities to master
- Modify cluster_master.py to handle client capabilities and model distribution
- Update config.html template to dynamically show/hide backend options
- Update web.py config route to handle dynamic backend availability
- Add model file transfer functionality between master and clients
- Update worker processes to handle model downloads from master
- Test GPU detection and configuration
- Update API documentation for new capabilities

Features implemented:
- Automatic detection of NVIDIA CUDA and AMD ROCm GPUs
- Dynamic configuration of analysis/training backends based on available hardware
- Cluster clients report GPU capabilities to master
- Model distribution from master to clients when needed
- Admin config page hides unavailable backend options
- Updated API documentation reflecting new GPU detection capabilities

- Add --client mode with required --cluster-host, --cluster-port, --token options
