[Enhancement] Upgrade DLedger to 0.3.3-SNAPSHOT

[leizhiyuan]

Before Creating the Enhancement Request

• I have confirmed that this should be classified as an enhancement rather than a bug/feature.

Summary

Upgrade RocketMQ's DLedger dependency to 0.3.3-SNAPSHOT.

Motivation

RocketMQ currently depends on DLedger 0.3.2. Upgrading to 0.3.3-SNAPSHOT helps RocketMQ keep aligned with the latest DLedger changes and removes the need to keep the corresponding fastjson1 dependency in RocketMQ, because the newer DLedger version no longer depends on fastjson1.

Describe the Solution You'd Like

Upgrade the DLedger version from 0.3.2 to 0.3.3-SNAPSHOT and adapt RocketMQ to the related DLedger API changes, including:

• Update moved DLedger future classes to the new package.
• Replace deprecated or removed DLedger configuration and store APIs.
• Adapt DLedger controller state machine code to the new apply iterator API.
• Remove the obsolete fastjson1 dependency and use fastjson2 where necessary.

Describe Alternatives You've Considered

Keep using DLedger 0.3.2 and retain the existing dependency setup. However, this leaves RocketMQ behind the latest DLedger updates and keeps the no-longer-needed fastjson1 dependency in the project.

Issue Evaluation

Category: type/enhancement | Status: Evaluated

Feasibility: feasible
Scope: DLedger integration layer — dledger module, controller state machine, pom.xml dependency management
Compatibility: Low risk — DLedger 0.3.3 is a minor version bump; API adaptations are clearly scoped (future class package moves, config/store API changes, controller apply iterator API). Removing fastjson1 in favor of fastjson2 aligns with the broader project direction.

This is a well-defined dependency upgrade with clear motivation (fastjson1 removal + DLedger alignment). The scope and adaptation points are well documented.

If you already have a PR in progress, feel free to link it. Otherwise, an automated fix proposal can be generated — reply to proceed.
