Ryubing MCP Bridge v0.2.0 (Windows x64)

Experimental Windows x64 build of Ryubing with the opt-in local MCP control bridge.

Highlights

• Adds cross-program RomFS access for multi-program containers and applies mods using the exact child program ID.
• Rejects bridge screenshots with INVALID_STATE until a non-zero renderer frame is ready, preventing early Vulkan screenshot null dereferences.
• Makes AsyncWorkQueue.Dispose idempotent so repeated Avalonia close notifications do not raise a disposal exception.
• Retains the loopback-only, token-authenticated MCP bridge with status, input, touch, screenshot, log, and game-launch support.

Build and verification

• Product version: 1.0.0-mcp.2+7231e00ea0302dd61b617b4edc29672b3dbcda30.
• Windows x64 self-contained Release build passed with 0 warnings and 0 errors.
• New idempotent-dispose regression test passed.
• The broader upstream test run was attempted but its existing Unicorn CPU host terminated with a stack overflow on this machine; this occurred outside the changed MCP paths.
• ZIP contains 13 runtime/license files only. No PDBs, logs, games, keys, firmware, profiles, or saves are included.

The bridge remains disabled during normal standalone launch. It is enabled only with --control-port and a token supplied via RYUBING_CONTROL_TOKEN or --control-token-file.
