refactor: Add override keyword to virtual function overrides in Tools and set compile option -Wsuggest-override

[bobtista]

Summary

• Add override keyword to virtual function overrides in Tools (WorldBuilder, GUIEdit, wdump)
• Add -Wsuggest-override compiler warning for GCC and Clang
• Add missing virtual keyword to ParticleSystemManagerDummy overrides in Core (missed in refactor: Add override keyword to virtual function overrides in GameEngine (2) #2392 since the class was added after that PR merged)
• Changes across Core, Generals and GeneralsMD

Context

Part 6/6 of splitting #2101. Depends on #2389 merging first.

Notes

• 201 files changed
• All lines retain the virtual keyword
• The -Wsuggest-override compiler warning ensures future virtual overrides use the keyword

Greptile Summary

This PR is the final installment (Part 6/6) of a large refactoring series that adds the override keyword to virtual function overrides across the Tools (WorldBuilder, GUIEdit, wdump) in both Generals and GeneralsMD, and enables the -Wsuggest-override GCC/Clang warning to enforce it going forward. It also adds the missing virtual keyword to ParticleSystemManagerDummy overrides in Core (a catch from #2392).\n\nKey changes:\n- 201 header and source files across Generals/, GeneralsMD/, and Core/ receive override annotations on virtual function overrides — no logic is changed.\n- cmake/compilers.cmake adds -Wsuggest-override for non-MSVC, non-VS6 toolchains so any future override missing the keyword will be flagged by the compiler.\n- PlaceholderView::isZoomLimited() in both wbview3d.cpp files gains const alongside override — this is a silent correctness fix, since View::isZoomLimited() is declared const in the base class and the original stub was inadvertently creating a separate (non-overriding) function that shadowed the base class virtual.\n- Four methods in PlaceholderView (isDoingScriptedCamera, stopDoingScriptedCamera, lookAt, initHeightForMap) are still missing override in both wbview3d.cpp files despite having matching signatures in the base View class. With -Wsuggest-override now active, these will produce compiler warnings on GCC/Clang builds.

Confidence Score: 4/5

Safe to merge; only style refactoring with one minor gap that will emit compiler warnings from the newly added flag.

The PR is a mechanical refactor with no logic changes. The sole substantive issue is that four PlaceholderView overrides in both wbview3d.cpp files are missing override, which will generate -Wsuggest-override warnings from the flag this very PR introduces. That inconsistency is worth resolving in this PR, but it does not affect runtime behaviour or build correctness.

Generals/Code/Tools/WorldBuilder/src/wbview3d.cpp and GeneralsMD/Code/Tools/WorldBuilder/src/wbview3d.cpp — four PlaceholderView overrides are still missing the override keyword.

Important Files Changed

Filename	Overview
cmake/compilers.cmake	Adds -Wsuggest-override for non-MSVC non-VS6 compilers in the correct branch; MSVC equivalent deferred to a future PR per previous review discussion.
Core/GameEngine/Include/GameClient/ParticleSys.h	Adds virtual to ParticleSystemManagerDummy override declarations to match codebase conventions; was missed in the prior PR (#2392).
Generals/Code/Tools/WorldBuilder/src/wbview3d.cpp	Adds override to most PlaceholderView overrides; also correctly adds const to isZoomLimited to match View::isZoomLimited() const; four pure/virtual overrides (isDoingScriptedCamera, stopDoingScriptedCamera, lookAt, initHeightForMap) are missing override and will trigger the newly enabled -Wsuggest-override warning.
GeneralsMD/Code/Tools/WorldBuilder/src/wbview3d.cpp	Same as Generals counterpart; override correctly added to most PlaceholderView overrides, but isDoingScriptedCamera, stopDoingScriptedCamera, lookAt, and initHeightForMap are still missing override.
Generals/Code/Tools/GUIEdit/Include/GUIEditDisplay.h	Adds override to all GUIEditDisplay virtual function overrides; setBorderShroudLevel gains both virtual and override for consistency.
GeneralsMD/Code/Tools/wdump/wdump.cpp	Adds override to CWDumpCommandLineInfo::ParseParam and CAboutDlg::DoDataExchange; straightforward.
Generals/Code/Tools/WorldBuilder/src/WorldBuilderDoc.cpp	Adds override to three local OutputStream subclass write() overrides; no logic changes.
Generals/Code/Tools/WorldBuilder/src/WorldBuilder.cpp	Adds override to WBGameFileClass::Set_Name, WB_W3DFileSystem::Get_File, and CAboutDlg::DoDataExchange; no logic changes.

Comment:
**Missing `override` will trigger `-Wsuggest-override` warnings**

This PR enables `-Wsuggest-override` in `cmake/compilers.cmake`, but `PlaceholderView` in this file still has several functions that override base class virtuals without the `override` keyword. These will produce warnings on GCC/Clang builds:

- `isDoingScriptedCamera()` — pure virtual in `View`
- `stopDoingScriptedCamera()` — pure virtual in `View`
- `lookAt(const Coord3D *o)` — virtual in `View`
- `initHeightForMap(void)` — virtual in `View`

The same four functions in `GeneralsMD/Code/Tools/WorldBuilder/src/wbview3d.cpp` (lines 200–204) have the same omission.

Note: `scrollBy(Coord2D *delta)` and `resetCamera`/`rotateCamera`/etc. are intentionally left without `override` because their signatures differ from the base class (missing the `easeIn`/`easeOut` default parameters or a missing `const` qualifier), so `override` would cause a compile error there.

```suggestion
	virtual Bool isDoingScriptedCamera() override { return false; }
	virtual void stopDoingScriptedCamera() override {}

	virtual void lookAt( const Coord3D *o ) override {};
	virtual void initHeightForMap( void ) override {};
```

How can I resolve this? If you propose a fix, please make it concise.

Might want to do a quick spacing check before I review?

Looks good - found some mixed tab/space stuff for indentation but the override {} spacing seems good

This looks good
