## Summary by CodeRabbit

- **New Features**
  - Added support for incremental broker data registration when single topic registration is disabled.

- **Refactor**
  - Updated broker registration logic to handle registration results explicitly and introduced a placeholder for future result processing.
  - Removed the incremental broker data registration method from the outer runtime and adjusted method signatures for improved clarity.

body: ## Pull Request Overview

This PR implements the incremental broker data registration feature by updating the registration flow in the broker runtime. Key changes include:
- Replacing the unimplemented branch with a call to BrokerRuntimeInner::register_increment_broker_data.
- Removing the now-unused register_increment_broker_data method from BrokerRuntime.
- Adding a placeholder for handling registration results in BrokerRuntimeInner.

`1188-1212`: _⚠️ Potential issue_

**`handle_register_broker_result` is called but does nothing – registration feedback silently lost**

`do_register_broker_all` now forwards the vector of `RegisterBrokerResult` to
`handle_register_broker_result`, yet that method is still a stub.  
All information returned by the namesrv (e.g. HA server addr, master/slave info,
order-config consistency) is therefore discarded.

```rust
this.handle_register_broker_result(result, check_order_config);
```

Until this is implemented the broker will not:

* update `broker_member_group`,
* refresh master HA / controller metadata,
* verify order-config when `check_order_config == true`.

This can lead to runtime inconsistencies and failed reads/writes after a topology
change.

Proposed minimal follow-up (skeleton only):

```diff
-    pub(self) fn handle_register_broker_result(
-        &mut self,
-        _register_broker_result: Vec<RegisterBrokerResult>,
-        _check_order_config: bool,
-    ) {
-        warn!("handle_register_broker_result not implemented");
-    }
+    pub(self) fn handle_register_broker_result(
+        &mut self,
+        register_broker_result: Vec<RegisterBrokerResult>,
+        check_order_config: bool,
+    ) {
+        for r in register_broker_result {
+            // 1. update HA / master addr
+            if let Some(ha_addr) = &r.ha_server_addr {
+                self.broker_config.ha_server_addr = ha_addr.clone();
+            }
+
+            // 2. sync broker member group
+            self.broker_member_group.merge_register_result(&r);
+
+            // 3. optional order-config validation
+            if check_order_config {
+                self.verify_order_config(&r);
+            }
+        }
+    }
```

Even a simplified implementation that logs the important fields would be safer
than ignoring them entirely.

`429-448`: **Validate `DataVersion` capture & consider updating _inside_ the async task**

`data_version` is cloned **before** the async block is spawned.  
If another thread mutates `self.data_version` between the clone and the eventual execution of the task, the `namesrv` will receive a stale version and may reject the incremental registration as out-of-date.

Two lightweight alternatives:

```diff
-        let data_version = self.data_version.as_ref().clone();
-        tokio::spawn(async move {
+        tokio::spawn({
+            let data_version = data_version.clone(); // capture just-in-time
+            async move {
                 ...
             }
         });
```

Or capture an `ArcMut<DataVersion>` and read the freshest value inside the task.

Please double-check whether version drift is acceptable for your protocol; otherwise consider the adjustment.

`40-41`: **Import looks correct**

Adding `RegisterBrokerResult` is necessary for the new result-handling logic.
No issues spotted.

`1146-1163`: <details>
<summary>❌ Incorrect review comment</summary>

**Potential contention: taking a mutable `ArcMut` while awaiting remote I/O**

`do_register_broker_all` now takes `mut this: ArcMut<…>` and holds a mutable
reference across the whole `await` to `broker_outer_api.register_broker_all`.
If `ArcMut` is implemented with interior locking (e.g. `RwLock`/`Mutex`), other
tasks trying to take a mutable reference will be blocked until the network call
finishes, which could be 10 s (`register_broker_timeout_mills`).

Consider cloning an `Arc<BrokerOuterAPI>` or restructuring so the long-running
I/O does not require a mutable borrow of the entire runtime.

**Ignore lock‐contention concern: ArcMut is lock-free**  
ArcMut wraps `Arc<SyncUnsafeCell<T>>` (no `Mutex`/`RwLock`), so taking a `mut this: ArcMut<…>` does _not_ acquire any blocking lock across the `.await`. The suggested refactor for avoiding lock contention isn’t needed.

## Walkthrough

This change removes the `register_increment_broker_data` method from the `BrokerRuntime` struct and refactors the broker registration process within `BrokerRuntimeInner`. The `do_register_broker_all` method now explicitly handles registration results by invoking a new private method, `handle_register_broker_result`, which currently serves as a placeholder for future implementation. Additionally, the `register_broker_data` method in `TopicConfigManager` is updated to replace an unimplemented code path with an asynchronous call to the broker registration logic, enabling incremental broker data registration when single topic registration is disabled.

| rocketmq-broker/src/broker_runtime.rs                                   | Removed `register_increment_broker_data` from `BrokerRuntime`; refactored `do_register_broker_all` to handle results; added private `handle_register_broker_result` method; updated imports. |
| rocketmq-broker/src/topic/manager/topic_config_manager.rs               | Updated `register_broker_data` to call broker registration logic asynchronously instead of panicking when single topic registration is disabled. |

### Chat

There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai?utm_source=oss&utm_medium=github&utm_campaign=mxsm/rocketmq-rust&utm_content=3219):

- Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  - `I pushed a fix in commit <commit_id>, please review it.`
  - `Generate unit testing code for this file.`
  - `Open a follow-up GitHub issue for this discussion.`
- Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples:
  - `@coderabbitai generate unit testing code for this file.`
  -	`@coderabbitai modularize this function.`
- PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  - `@coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.`
  - `@coderabbitai read src/utils.ts and generate unit testing code.`
  - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.`
  - `@coderabbitai help me debug CodeRabbit configuration file.`

### Support

Need help? Create a ticket on our [support page](https://www.coderabbit.ai/contact-us/support) for assistance with any issues or questions.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

### CodeRabbit Commands (Invoked using PR comments)

- `@coderabbitai pause` to pause the reviews on a PR.
- `@coderabbitai resume` to resume the paused reviews.
- `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository.
- `@coderabbitai full review` to do a full review from scratch and review all the files again.
- `@coderabbitai summary` to regenerate the summary of the PR.
- `@coderabbitai generate docstrings` to [generate docstrings](https://docs.coderabbit.ai/finishing-touches/docstrings) for this PR.
- `@coderabbitai generate sequence diagram` to generate a sequence diagram of the changes in this PR.
- `@coderabbitai resolve` resolve all the CodeRabbit review comments.
- `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository.
- `@coderabbitai help` to get help.

### Other keywords and placeholders
