Segmentation fault on Windows ARM64 #10302

Description

OpenCode crashes with "Segmentation fault" when running on Windows ARM64 (under x64 emulation).

Environment:

OS: Windows 11 ARM64
OpenCode version: 1.1.32
Installation method: npm (npm install -g opencode-ai)
Architecture: ARM64 running x64 binary via emulation
Steps to reproduce:

Install OpenCode: npm install -g opencode-ai
Run: opencode or opencode --port 34802
Observe: Segmentation fault
Expected: OpenCode TUI or server starts
Actual: Segmentation fault

Additional context:

The binary launches and loads config (visible in logs at ~/.local/share/opencode/log/)
Crash occurs after initial setup, before UI renders
Likely related to Bun runtime x64 emulation on ARM64
Request: Native ARM64 Windows build, or investigation into emulation compatibility.
