[PWGHF] Implementation of MassLike/MassUnlike Columns and Move TPC–TOF PID Cuts to electronSelectionWithTPCEmcal.cxx

[rashigupt]

Added two new columns in electronSelectionWithTPCEmcal.cxx:

MassLike for like-sign electron pairs

MassUnlike for unlike-sign electron pairs

Implemented the TPC–TOF selection conditions inside electronSelectionWithTPCEmcal.cxx to ensure electron PID cuts are applied consistently at the selection stage.

Removed the TPC–TOF condition from correlatorHFeHadron.cxx since it is now handled entirely in the electron selection step.

@rashigupt Don't open your PR as ready for review if it fails the tests.
The PR title is very ambiguous. As it is, it's just a statement that something is OK. That's not a reason to modify the code. You should state what changes are made by the PR.

Dear expert, please tell me why it does not build?

Dear expert, please tell me why it does not build?

Dear @rashigupt , please read the contribution guidelines. It is all explained there.

[rashigupt]

I was able to build the code successfully on my local machine, but it failed in the build system. Could you kindly help me understand the reason for this failure?

Dear @rashigupt ,

• I had explicitly asked you to not mark your PR as ready for review if it fails the tests! You did it again!
• More importantly, your PR completely replaces the content of PWGHF/HFC/DataModel/CorrelationTables.h with the content of PWGHF/HFL/DataModel/ElectronSelectionTable.h! This is why the builds failed. Your PR cannot compile on any machine so I don't believe your claim that you were able to build the code successfully on your local machine.
• Test your changes properly before you make a PR and stop wasting time and resources of your colleagues!
• Btw, the PR title is still too vague.

[rashigupt]

Dear Vit,

I sincerely apologize for the mistake.
Due to an error on my side, the wrong file got replaced and that caused the build failure. I understand that this created unnecessary work for you and the team.

I will fix the file immediately, ensure the code compiles locally, and run the full set of tests before marking the PR as ready for review again.

Thank you for pointing it out, and sorry again for the inconvenience.

[vkucera]

Thanks @rashigupt for the fixes.

[rashigupt]

Dear expert, please approve and merge the code.

Dear expert, if you have no further comments, kindly approve and merge the code.
