style: apply clang-format to new dd4hepplugins files (PR #266)

[Copilot]

New files added by the DD4hep integration PR (#266) did not comply with the repo's .clang-format policy. This PR applies the correct formatting to all new C/C++ sources under dd4hepplugins/.

Changes

• SpacesInParentheses: true / SpaceBeforeParens: Never — all call sites and control-flow conditions reformatted:

  // before
  if (!pv) return -1;
  sev->beginOfEvent(eventID);
  
  // after
  if( !pv )
      return -1;
  sev->beginOfEvent( eventID );

• AlignConsecutiveDeclarations / AlignConsecutiveAssignments — variable groups column-aligned:

  G4double Pmin  = Rindex->Energy( 0 );
  G4double Pmax  = Rindex->GetMaxEnergy();
  G4double nMax  = Rindex->GetMaxValue();
  G4double beta1 = step->GetPreStepPoint()->GetBeta();

• Member initializers — int x{0} → int x{ 0 }
• Namespace closing comments — } // namespace → } // namespace
• Macro calls — DDG4_DEFINE_ACTION_CONSTRUCTORS(X) → DDG4_DEFINE_ACTION_CONSTRUCTORS( X )

No behavioral changes — formatting only.

Original prompt

Review pull request #266 in repository BNLNPPS/eic-opticks and create a PR that updates the newly added files so they comply with the repository's current style policy as enforced by .clang-format and the cpp-linter job in .github/workflows/build-pull-request.yaml.

Repository: BNLNPPS/eic-opticks
Upstream PR being reviewed: #266 ("Dd4hep integration")

Relevant style policy:

• .clang-format is based on Microsoft style with:
  • ColumnLimit: 0
  • DerivePointerAlignment: true
  • ReferenceAlignment: Pointer
  • SpaceBeforeParens: Never
  • SpacesInParentheses: true
  • SortIncludes: false
  • ReflowComments: false
  • AlignTrailingComments: false
  • AlignConsecutiveDeclarations: Consecutive
  • AlignConsecutiveAssignments: Consecutive
• cpp-linter workflow settings from .github/workflows/build-pull-request.yaml:
  • style: file
  • ignore: include/argparse
  • lines-changed-only: true
  • thread-comments: true
  • format-review: true
  • tidy-checks: '-*'

Scope:

• Focus on the new files introduced by PR feat(dd4hep): add experimental DDG4 integration plugins and examples #266, especially the new C/C++ sources and headers under dd4hepplugins/ and any other newly added C/C++ files in the PR.
• Ensure formatting matches .clang-format exactly.
• Adjust only style/formatting and linter-compliance issues; do not change intended behavior.
• If there are workflow-relevant stylistic issues in newly added CMake files that should be cleaned up for consistency, include those too, but prioritize files checked by cpp-linter.

Files added in the PR include new C++ headers/sources such as:

• dd4hepplugins/CMakeLists.txt
• dd4hepplugins/DD4hepSensorIdentifier.hh
• dd4hepplugins/OpticsEvent.cc
• dd4hepplugins/OpticsEvent.hh
• dd4hepplugins/OpticsRun.cc
• dd4hepplugins/OpticsRun.hh
• dd4hepplugins/OpticsSteppingAction.cc
• dd4hepplugins/OpticsSteppingAction.hh
• dd4hepplugins/examples/CMakeLists.txt
• dd4hepplugins/examples/geometry/Raindrop_geo.cpp

Please create a pull request with the style-only fixes.

The following is the prior conversation context from the user's chat exploration (may be truncated):

User: Since all of these files are new, can we make sure they comply with the current style policy defined in .clang-format and the cpp-linter workflow job?

Assistant: We’re waiting for your response to the pull request creation prompt before I can continue.
