fix: use getOpenCodeConfigDir in bun-install to avoid startup warning

[kristianvast]

Summary

• Fix: bun-install.ts used getConfigDir() from config-context.ts, which requires initConfigContext() to be called first. The auto-update checker hook calls runBunInstall() on startup, but hooks never go through the installer path where initConfigContext() is called — causing a console.warn on every startup for all users.
• Change: Switch to getOpenCodeConfigDir() from shared/ which resolves config paths directly without requiring prior initialization.
• Impact: Removes the [config-context] getConfigContext() called before initConfigContext(); defaulting to CLI paths. warning visible in the TUI on every launch.

Root Cause

bun-install.ts lives in cli/config-manager/ (installer module) but is also imported by the auto-update checker hook via background-update-check.ts. The installer path calls initConfigContext() before any config access, but the hook path does not — triggering the fallback warning in getConfigContext().

The NODE_ENV !== "production" guard was intended to suppress this in production, but Bun's bundler doesn't set NODE_ENV=production, so the warning fires for everyone.

Summary by cubic

Fixes the startup console warning by switching bun-install to getOpenCodeConfigDir, and updates model fallbacks/migrations to prefer OpenAI gpt-5.3-codex. This removes the TUI warning on launch and keeps configs/tests aligned with the new default.

• Bug Fixes

  • Use getOpenCodeConfigDir({ binary: "opencode" }) in bun-install to avoid config-context init in the auto-update hook path.
  • Adjust timeout message to reference the correct config directory.

• Refactors

  • Update agent/category fallback chains from gpt-5.2 to gpt-5.3-codex.
  • Add migration map openai/gpt-5.3 → openai/gpt-5.3-codex and update tests accordingly.

Confidence score: 2/5

• There is a high-confidence compatibility regression in src/cli/config-manager/bun-install.ts: hardcoding binary: "opencode" is likely to break OpenCode Desktop installation behavior by forcing installs into the CLI directory.
• src/cli/model-fallback-requirements.ts includes an unexpected model bump (gpt-5.2 → gpt-5.3-codex) outside the stated fix scope, which raises regression risk for fallback behavior and makes the change harder to validate safely.
• Provider mappings for gpt-5.3-codex appear inconsistent in both src/shared/model-requirements.ts and src/cli/model-fallback-requirements.ts (notably github-copilot), and while some related entries may be pre-existing, these touched inconsistencies still increase merge risk.
• Pay close attention to src/cli/config-manager/bun-install.ts, src/cli/model-fallback-requirements.ts, and src/shared/model-requirements.ts - installation compatibility and provider/model mapping consistency need verification before merge.
