Modernize Index module to use modern record extensions

[mwihoti]

Description

Modernize the Index module to use modern Haskell record extensions (DuplicateRecordFields, NoFieldSelectors, OverloadedRecordDot) instead of RecordWildCards.This change replaces record wildcard patterns with explicit dot notation field access, making the code more maintainable and aligned with modern Haskell best practices.

• Updated Index/CompactAcc.hs:

  • Add modern record extensions
  • Replace IndexCompactAcc{..} wildcards with explicit parameter binding and dot notation
  • Update all field accesses to use ica.field syntax

• Updated Index/Compact.hs:

  • Add modern record extensions
  • Replace IndexCompact{..} wildcards with explicit parameter binding and dot notation
  • Update all field accesses to use idx.field syntax
  • Fix countClashes, hasClashes, sizeInPages to use lambda syntax

• Updated test file test/Test/Database/LSMTree/Internal/Index/Compact.hs:

  • Add modern record extensions
  • Replace field selector function calls with dot notation
    pilot for (Use DuplicateRecordFields, NoFieldSelectors, and OverloadedRecordDot #811)

Hello, @jorisdral I've made a pr that modernizes the Index module by adopting modern language extensions. Ready for review. I plan to work on Internal/Merge.hs and Internal/RunAcc.h next.

@mwihoti I think your fork's main branch and lsm-tree's main branch are out of date, causing a lot of git conflicts and outdated information. You should sync your fork's main branch and rebase your feature/911-modern-record-extensions branch on top of your fork's main branch

Hi @jorisdral, hope you are well sorry about the conflicts, I've rebased the branch, no more conflicts. if everything is good I plan to work on Internal/Merge.hs and Internal/RunAcc.hs. Thanks

There are still some merge conflict artifacts, see https://github.com/IntersectMBO/lsm-tree/pull/860/files
