feat(router): support static script router config

[leno23]

What

• Add SetStaticConfig support to ScriptRouter for application-scoped static router configs.
• Compile static JavaScript rules the same way dynamic config-center updates are compiled.
• Add regression coverage for enabled, disabled, and non-script static configs.

Why

Issue #3203 tracks router follow-ups and explicitly calls out that RouterConfig already has ScriptType and Script fields, but ScriptRouter did not implement the static config interface.

Validation

• go test ./cluster/router/script
• go test ./cluster/router/...
• git diff --check

Pull request overview

Adds static (application-scoped) router config injection support for ScriptRouter, enabling bootstrap configuration via RouterConfig without YAML parsing and aligning static compilation behavior with config-center updates. This addresses the gap noted in #3203 where RouterConfig already includes ScriptType/Script but ScriptRouter didn’t implement the static config interface.

Changes:

• Implement SetStaticConfig(*global.RouterConfig) on ScriptRouter to accept static script rules and compile them on set.
• Ensure static updates replace any previously compiled script state (destroy old, compile new; disabled/invalid disables routing).
• Add regression tests covering enabled/disabled/unsupported/invalid static script configs.

The failed Integration Test appears to be runner infrastructure rather than a code failure. The failing step ended with link: mapping output file failed: no space left on device while building the router/tag sample. I tried to rerun the failed job, but I do not have repository admin rights to rerun Actions. Please rerun the failed Integration Test when convenient.
