feat(ai-gateway): add zhipuai extended options with dynamic config

[johnlanni]

Summary

This PR adds extended configuration options for the Zhipu AI provider with a refactored approach that allows dynamic configuration without rebuilding the Docker image.

Key Changes

1. Configuration is built in get-ai-gateway.sh - The ZHIPUAI_EXTRA_CONFIGS environment variable is constructed from individual settings
2. Passed to container via environment - The config is stored in the config file and passed to the container at runtime
3. Parsed in ai-gateway.sh - The container script parses the comma-separated config string

New CLI Options

Option	Description
--zhipuai-domain DOMAIN	Specify the Zhipu AI API domain (default: open.bigmodel.cn, international: api.z.ai)
--zhipuai-code-plan-mode	Enable Code Plan mode (uses /api/coding/paas/v4/chat/completions endpoint)

Usage Examples

# Use international endpoint
bash get-ai-gateway.sh --zhipuai-key $API_KEY --zhipuai-domain api.z.ai

# Enable Code Plan mode
bash get-ai-gateway.sh --zhipuai-key $API_KEY --zhipuai-code-plan-mode

# Combine both options
bash get-ai-gateway.sh --zhipuai-key $API_KEY --zhipuai-domain api.z.ai --zhipuai-code-plan-mode

Architecture

get-ai-gateway.sh                    ai-gateway.sh (in container)
┌─────────────────────┐              ┌─────────────────────┐
│ Parse CLI args      │              │ Read env variable   │
│ --zhipuai-domain    │──────────────│ ZHIPUAI_EXTRA_CONFIGS│
│ --zhipuai-code-plan │   env var    │                     │
│                     │              │ Parse & apply to    │
│ Build EXTRA_CONFIGS │              │ provider config     │
└─────────────────────┘              └─────────────────────┘

Benefits

• No image rebuild needed - Configuration changes take effect by restarting the container
• Consistent with existing pattern - Uses the same LLM_ENVS mechanism as other settings
• Backward compatible - Default behavior unchanged when options not specified
