Updated PR: Comment transition detection in block tracking

[parinaz-st]

Support for uncommented Block detection, Comment statement transition detection for matched blocks

[parinaz-st]

Update:
I've continued improving this feature since opening the PR.
I've added support for uncommented block detection involving:
-reconstruction of multiline block signatures from both // and /* */ comments
-block signatures with the opening brace on the following line
-braceless control blocks
-multiple block signatures within a single block comment

I also refined the commented-out/uncommented code detection for matched blocks.
In cases where one statement is commented out and a similar statement is uncommented within the same commit,
RefactoringMiner may match the two statements as a mapping with replacements, so they no longer appear in the commentedOut and unCommented collections.
The implementation now inspects these mappings and compares them against the added/deleted comments to correctly identify the comment transition.
Finally, I started identifying uncommented block cases in real-world repositories and validating the implementation against them. I'll continue extending the implementation as I encounter additional real-world scenarios.
