Subject: [PATCH] fix(sisyphus-agent): handle OpenCode installer failure with
 pinned version fallback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace retry loop with intelligent fallback strategy:
- Try default installer first (better for version discovery)
- On failure, fallback to pinned version 1.0.204
- Handle corrupted downloads with direct fallback install

This addresses the sisyphus-agent workflow failure where OpenCode's installer failed
with 'Failed to fetch version information' error.
