Feature Request: Customizable Status Line

Claude Code supports a statusline setting in ~/.claude/settings.json that lets users display arbitrary info (git branch, time, costs, etc.) in the bottom bar.
It would be great if OpenCode had something similar — ideally a small DSL or template string in tui.json that renders into the status bar.

Specific use case: Go usage at a glance

As a Go subscriber, I'd love to see my usage for the current period directly in the TUI status line, e.g.:
Go: 42% (5h) | 38% (week) | 25% (month)
Right now I have to open opencode.ai/auth in a browser to check. Having this info persist in the terminal would save a lot of context switching.

What I'm imagining

// tui.json
{
  "statusline": {
    "left": "{git:branch} {go:usage_5h}",
    "right": "{model} {go:usage_week} | {go:usage_month}"
  }
}
Or even simpler — just expose the Go usage via an API/env that I could pipe into a plugin hook or a custom command.
Alternatives considered
- Using the plugin system — but there's no hook to modify the TUI chrome/status bar
- Using status_view (<leader>s) — useful but not persistent/glanceable
- Web console — works but breaks flow
Would love to hear if there's already a way to do this, or if this is something the team would consider adding.

This issue might be a duplicate of existing issues. Please check:

• [FEATURE]: Native StatusLine Hook for Plugins (Context-Free Display) #8619: Very similar request for a native StatusLine hook for plugins in the TUI, also referencing Claude Code's statusline feature as inspiration
• [FEATURE]: Toggleable top-bar status header — session title, context, cost, MCP/LSP status, git branch #25262: Related request for a toggleable top-bar status header showing session info (tokens, cost, MCP/LSP, git branch) in the TUI
• [FEATURE]: Add Go plan usage/balance API endpoint (rolling/weekly/monthly windows) #16017: Related request specifically for exposing Go plan usage/balance via a public API endpoint (rolling/weekly/monthly windows)

These issues cover the two core components of this request — the customizable TUI status line and the Go usage data access.

There is a plugin API that will be official soon that allows to do that as a TUI plugin. It's already in the production version, just not officially documented yet. If you point OpenCode at it should be able to figure it out and build a local local plugin that shows the info you need.
