Description
### Before Creating the Enhancement Request
- [x] 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.
### Additional Context
A corresponding pull request will be linked to this issue.
Contributor guide
Research direction
Start by locating RocketMQ's DLedger 0.3.2 dependency and the DLedger future, configuration, store, controller state machine, and fastjson1 usages described in the issue. Review the DLedger 0.3.3-SNAPSHOT API changes, then verify the project builds and tests pass with fastjson1 removed and the affected APIs adapted.
