feat: MCP Remote Control via devbench

[SkrubbySkrubInAShrub]

Summary

Adds a new Remote Control CORE feature that lets AI assistants (Claude Code, Cursor, Continue, etc.) query and mutate runtime state for A/B testing and performance investigation — via the external devbench SKSE plugin over its cross-plugin C-ABI.

Cherry-picked from alandtse/open-shaders: #27, #62, #66.

Changes

feat(remote-control): add MCP server core feature (#27)

• New RemoteControl CORE feature, off by default, appears under Core Features → Utility in the in-game menu
• Wires GetSingleton, DataLoaded, DrawSettings, and global registration into Globals.h

feat(mcp): shader recompile observability (#62)

• New inspect(kind='shadercache') tool returning { compiling, completedTasks, totalTasks, failedTasks, currentFailedCount, frame_count } — poll to confirm hot-reloaded shaders finished (or failed) recompiling without log-diving
• Tracy TracyMessage / TracyMessageC annotations at shader compile completion, #ifdef TRACY_ENABLE-guarded
• Decoupled via ShaderCompileStatus.h to avoid a using namespace std::chrono leakage from ShaderCache.h into vendored httplib headers

feat(mcp): integrate devbench (#66)

• Drops the embedded cpp-mcp server; registers openshaders.* tools into the standalone devbench host via DevBenchBridge over the DevBenchAPI C-ABI
• Gated behind option(DEVBENCH_BRIDGE ON) (default on); -DDEVBENCH_BRIDGE=OFF compiles to a no-op stub with no added dependency
• devbench-api is a self-contained vcpkg overlay port under cmake/ports/devbench-api
• RemoteControl.cpp is now a ~120-line read-only status panel reporting devbench host presence, bound port (polled from devbench/runtime.json every 2s), and the registered tool list

Tools exposed through devbench

Tool	Operations
openshaders.feature	list / get / set / reset / toggle features
openshaders.inspect	engine state, shader-cache status
openshaders.shadercache	clear / delete compiled cache
openshaders.capture	RenderDoc / screenshot capture
openshaders.settings	save / load / reset global config

Console passthrough is provided by devbench itself.

Notes

• Requires the devbench SKSE plugin to be installed; degrades gracefully (status panel only) when the host isn't present
• No in-game server is hosted by this plugin — devbench owns the MCP/REST transport
