feat: auto-select plugin registry based on timezone

[johnlanni]

Summary

Auto-detect timezone and select the geographically closest plugin registry for faster WASM plugin downloads.

Problem

Currently, all plugin OCI URLs are hardcoded to use the Hangzhou registry (higress-registry.cn-hangzhou.cr.aliyuncs.com), which causes slow downloads for users in other regions.

Solution

Auto-detect timezone and select optimal registry:

Region	Timezone Examples	Selected Registry
China & nearby	Asia/Shanghai, Asia/Hong_Kong, etc.	higress-registry.cn-hangzhou.cr.aliyuncs.com
Southeast Asia	Asia/Singapore, Asia/Jakarta, etc.	higress-registry.ap-southeast-7.cr.aliyuncs.com
North America	America/, US/, Canada/*	higress-registry.us-west-1.cr.aliyuncs.com
Others	Default fallback	higress-registry.cn-hangzhou.cr.aliyuncs.com

Changes

1. Script Updates (get-ai-gateway.sh)

Add detectPluginRegistry() function:

• Detects timezone using timedatectl or /etc/timezone
• Selects optimal registry based on geographic region
• Supports manual override via PLUGIN_REGISTRY environment variable
• Prints selected registry for visibility

Add DEFAULT_PLUGIN_REGISTRY constant:

• Defaults to Hangzhou registry
• Used as fallback when auto-detection fails

Update resetEnv() function:

• Calls detectPluginRegistry() during initialization
• Sets PLUGIN_REGISTRY variable

Update config file generation:

• Write PLUGIN_REGISTRY to default.cfg
• Makes registry available to container scripts

2. Template Updates

scripts/config-template/ai-gateway.sh:

• Replace hardcoded oci://higress-registry.cn-hangzhou.cr.aliyuncs.com with oci://${PLUGIN_REGISTRY:-higress-registry.cn-hangzhou.cr.aliyuncs.com}
• Applies to:
  • ai-proxy plugin
  • ai-statistics plugin
  • model-router plugin

scripts/config-template/ai-proxy.sh:

• Replace hardcoded ai-proxy plugin URL with variable

Usage

Auto-detection (default):

./get-ai-gateway.sh start --non-interactive --dashscope-key sk-xxx
# Output:
# Auto-detected timezone: Asia/Shanghai
# Selected plugin registry: higress-registry.cn-hangzhou.cr.aliyuncs.com

Manual override:

PLUGIN_REGISTRY="higress-registry.ap-southeast-7.cr.aliyuncs.com" \
  ./get-ai-gateway.sh start --non-interactive --dashscope-key sk-xxx

Benefits

• Faster plugin downloads in non-China regions
• Transparent - auto-detects without user intervention
• Flexible - supports manual override
• Visible - prints selected registry to console
• Backward compatible - defaults to Hangzhou registry if detection fails

Testing

• Script syntax validation (bash -n)
• Auto-detection logic for different timezones
• Manual override via PLUGIN_REGISTRY env var
• Plugin URL substitution in all templates

Improves deployment experience for the higress-clawdbot-integration skill, which currently documents manual IMAGE_REPO selection for the all-in-one container image. Now plugins also benefit from the same geographic optimization.
