[Task] Design virtual thread support for ShenYu runtime and plugins

[Aias00]

Description

Background

A future ShenYu main repo change may use Java virtual threads to improve blocking IO handling in runtime and plugin execution paths.

Before implementation, we need a design that identifies where virtual threads are useful, where they are risky, and how to keep a fallback path.

Tasks

• Inventory current thread pool usage in bootstrap/runtime/plugin code.
• Identify blocking IO paths that may benefit from virtual threads.
• Identify CPU-bound paths that should not use virtual threads.
• Design a unified executor abstraction for plugin/runtime use.
• Define configuration flags for enabling/disabling virtual threads.
• Define fallback behavior when virtual threads are unavailable.
• Define observability requirements: thread naming, metrics, tracing, logs.
• Define benchmark scenarios comparing platform threads and virtual threads.
• Identify compatibility impact on plugins.

Expected Output

A virtual thread design proposal covering:

• Candidate execution paths
• Non-candidate execution paths
• Executor abstraction
• Configuration model
• Fallback model
• Benchmark plan
• Risk analysis

Acceptance Criteria

• The proposal does not require Java client code to upgrade JDK.
• The proposal includes a safe fallback path.
• The proposal includes measurable benchmark criteria.
