Minecraft Harness 0.1.1

Minecraft Harness 0.1.1

Fixes Codex process disconnected during startup on Windows, including GT New
Horizons in Prism Launcher. Java's native process argument serialization removed
the quotes in the world-local projects trust override. Codex rejected that value
before the protocol handshake. Harness now preserves quotes and backslashes at
the native process boundary without using a shell.

Replace the old Harness runtime JAR with
minecraft-harness-forge-1.7.10-0.1.1.jar while Minecraft is closed. Agent Tools
and Mira remain compatible at 0.1.0. World data, authentication and user settings
do not need changes.

Validation includes a native child-process regression for Windows argument
preservation and a local Codex 0.164.0 initialization check using the affected
GTNH world workspace. The protocol fixture baseline remains 0.163.0, so 0.164.0
still shows a compatibility warning. Full gameplay and a model response are not
covered by the initialization check.

Use Java 8 for Minecraft and a native Codex executable. The protocol baseline is Codex 0.163.0; other versions show a compatibility warning. Local saves and LAN hosting are supported; remote multiplayer workspaces are not implemented. Default CI validates compilation, tests, architecture and formatting. It does not launch Minecraft, a live Codex backend or real GPU tests.
