chore(build): remove submodules and relocate references to workspace

[fbraz3]

Summary

• Remove git submodules (references/fbraz3-dxvk, references/GameClient, references/GameServer) and .gitmodules from the GameClient repository.
• Relocate reference repositories (GameClient, GameServer) directly to the workspace-level ../references/ folder as clean standalone repositories on disk.
• Update cmake/dx8.cmake local fork mode (-DSAGE_DXVK_USE_LOCAL_FORK=ON) to detect the workspace sibling repository ../generalsx-dxvk by default.
• Update cmake/ngmp.cmake to detect ValveNetworkingSockets in ../references/GameClient when building for Windows MSVC.
• Update AGENTS.md, guidelines, instructions, and worklog documentation.

Technical Rationale

1. DXVK Submodule Redundancy: The references/fbraz3-dxvk submodule was never checked out or used in CI (CI builds fetch precompiled Linux binaries or clone pinned macOS commits directly via CMake FetchContent / ExternalProject). Locally, DXVK is already managed as a top-level workspace project (generalsx-dxvk).
2. References Relocation: Keeping reference submodules inside GameClient generated git status noise and unneeded submodule complexity. Moving them to the workspace references/ directory keeps them accessible for disk/code reference while keeping GameClient submodule-free.

Validation

• Verified git status in ../references/GameClient and ../references/GameServer are clean standalone repositories.
• Re-configured and compiled GeneralsXZH target on macOS (macos-vulkan) with 0 errors.

Summary by CodeRabbit

• Bug Fixes

  • Restored rating updates for eligible QuickMatch and CustomGame matches, including corrected winner and loser ratings and leaderboard updates.

• Build Improvements

  • macOS builds can locate the DXVK checkout in the workspace, with a fallback to the existing reference location.
  • Windows builds can find Valve networking libraries in an additional reference location.

• Documentation

  • Updated development guidance to reflect the current DXVK source and workspace layout.

📝 Walkthrough

Walkthrough

This change removes three submodule declarations, updates workspace reference paths and DXVK guidance, and adjusts CMake discovery for local DXVK and Windows GameNetworkingSockets files. It also adds two worklog entries, including one that records ELO processing and historical backfill.

Changes

Workspace paths and build discovery

Layer / File(s)	Summary
Workspace reference layout .gitmodules, AGENTS.md, .devin/wiki.json, .github/instructions/ngmp.instructions.md, docs/WORKLOG/2026-09-DIARY.md	Removes the three submodule declarations and documents GameClient and GameServer under the workspace-level ../references/ directory. The worklog records repository relocation and related path updates.
DXVK source guidance .github/instructions/*, .devin/wiki.json, AGENTS.md	Updates DXVK source references to generalsx-dxvk and narrows the macOS instruction scope. The fork branch remains generalsx-macos-v2.6.
CMake path discovery cmake/dx8.cmake, cmake/ngmp.cmake	Adds local DXVK checkout selection and a Windows MSVC GameNetworkingSockets lookup path.

ELO worklog entry

Layer / File(s)	Summary
ELO processing worklog docs/WORKLOG/2026-09-DIARY.md	Adds a diary entry describing ELO update handling, leaderboard synchronization, configuration parsing, deployment, and historical backfill.

Change: Other

Merge Risk: 🔵 Low · up to 9891a

Windows builds without the standalone networking library lose P2P, and the warning no longer gives valid setup guidance. This is a bounded build issue; correct the guidance before relying on that configuration.

Review details

Systems and components

• observed — cmake (service) was modified; 2 changed files map to changed impact.
• observed — AGENTS.md (service) was modified; 1 changed file maps to changed impact.
• observed — docs (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in AGENTS.md: The references/ directory description now identifies the workspace reference directory at ../references/ and lists GameClient and GameServer, replacing fbraz3-dxvk.
• observed — Modified behavior in AGENTS.md: The macOS instruction’s applyTo pattern drops references/fbraz3-dxvk/**, leaving scripts/build/macos/**.
• observed — Modified behavior in cmake/dx8.cmake: When DXVK_LOCAL_FORK_DIR is undefined, the configuration now checks for a Git checkout at ../generalsx-dxvk first, then references/fbraz3-dxvk, and defaults to ../generalsx-dxvk if neither exists. The option description now identifies the local generalsx-dxvk checkout; its OFF default is unchanged.
• observed — Modified behavior in cmake/ngmp.cmake: The Windows MSVC prebuilt-library search now also accepts the ../references/GameClient/.../GameNetworkingSockets.lib location and sets _VNS_DIR and _VNS_INC to its corresponding library and include directories.

Replace the obsolete submodule recovery command.

If the Windows MSVC fallback finds no prebuilt library, this warning tells the user to run git submodule update --init references/GameClient. This PR removes that submodule, so the command cannot restore the missing library. Point the warning to the workspace ../references/GameClient checkout or another supported installation path.
