[PR] fix(core): remove unreachable and bug-prone null guards in Attribute.equals [texera]
Alwaysgaurav1 opened a new pull request, #8267:
URL: https://github.com/apache/texera/pull/8267
### What changes were proposed in this PR?
In `Attribute.java` (`common/workflow-core/src/main/scala/org/apache/texera/amber/core/tuple/Attribute.java`), `Attribute.equals()` contained two unreachable null guards:
```java
if (this.attributeName == null) {
return that.attributeName == null;
}
if (this.attributeType == null) {
return that.attributeType == null; // ignores attribute name comparison!
}

<!-- texera:welcome-first-time-contributor -->
👋 Thanks for your first contribution to Texera, @Alwaysgaurav1!
If you're looking for a good place to start, browse issues labeled [`starter-task`](https://github.com/apache/texera/issues?q=is%3Aissue+is%3Aopen+label%3Astarter-task); they're scoped to be approachable for newcomers.
You can drive common housekeeping yourself by commenting one of these commands on its own line:
- **Issues.** Comment `/take` to assign an open issue to yourself, or `/untake` to release it. You can find unclaimed work with the search filter `is:issue is:open no:assignee`.
- **Sub-issues.** To link issues into a parent/child hierarchy, comment `/sub-issue #5166 #5222` on the parent to attach those children (or `/unsub-issue #5166 #5222` to detach them). From a child issue, comment `/parent-issue #5166` to set its parent, or `/unparent-issue` to clear it (the current parent is detected automatically). References may be written as `#5166` or as a bare `5166`; cross-repository references are not supported.
- **Pull requests (author only).** Comment `/request-review @user` to request a review from someone, or `/unrequest-review @user` to withdraw that request.
Each command must match exactly: `/take this` will not work, only `/take` does. For the full contribution flow, see [CONTRIBUTING.md](https://github.com/apache/texera/blob/main/CONTRIBUTING.md).

Thanks for the PR. Please follow the pull request template. Also, since this is not a bug fix, you may want to rename the PR title to use refactor. Temporarily marked it as a draft. Please feel free to mark it as ready for review once the PR is ready.

@Alwaysgaurav1, I'm sorry, this was my fault. You claimed #8149 and fixed it properly, but I merged the same change in #8339 without checking who was assigned. I'll assign myself to issues I plan to fix from now on, and I'm updating `AGENTS.md` (#8675) so agents check for existing claims first. If you'd like another issue, I'm happy to help you find one.
