[FEATURE] ThreadLocal handling with Virtual Threads (JDK21)

### 请描述您的需求或者改进建议
The project heavily relies on `ThreadLocal` objects, which can cause explosive memory growth with `Virtual Threads`. In theory, `ThreadLocals` have relatively no effect with Virtual Threads since its encouraged to create many and short lived threads, which would wipe the Thread Local objects. Also, there can exist millions of virtual threads, where `ThreadLocal` also can become a problem.

### 请描述你建议的实现方案
Utilise a different mechanism of recycling such objects. Currently Jackson has created a virtual thread friendly recycler.

Start by locating the project's ThreadLocal-based recyclers and reviewing how they behave under JDK 21 virtual threads. Compare the approach with Jackson's virtual-thread-friendly recycler, then define and validate a replacement that avoids excessive memory growth while preserving recycling behavior.
