[Bug]: tmux-integration's server health check failing due to incorrect url path

Prerequisites

• I will write this issue in English (see our Language Policy)
• I have searched existing issues to avoid duplicates
• I am using the latest version of oh-my-opencode
• I have read the documentation or asked an AI coding agent with this project's GitHub URL loaded and couldn't find the answer

Bug Description

Even with tmux.enabled=true, subagents won't spawn in separate tmux panes.
Based on code analysis, this is due to the health check at https://github.com/code-yeongyu/oh-my-opencode/blob/dev/src/shared/tmux/tmux-utils/server-health.ts#L13 using /health as the endpoint path to check server health (which returns a http 403 due to the endpoint not existing, therefore skipping tmux integration), while the actual endpoint in opencode is /global/health (see https://github.com/anomalyco/opencode/blob/dev/packages/opencode/src/server/routes/global.ts#L18-L21).

Steps to Reproduce

1. Configure oh-my-openocde.json with { "tmux": { "enabled":true } }
2. start opencode with opencode -p 4096
3. submit a query that uses subagents

Expected Behavior

agents should spawn in separate tmux pane splits

Actual Behavior

agents run in same window
