What does this PR do?

Free Zen models return FreeUsageLimitError with a long daily retry-after. The session retry policy treated that like a normal 429 and slept for hours (Free usage exceeded, subscribe to Go [retrying in 8h …]).

This change treats free_tier_limit and account_rate_limit as terminal: publish the existing Go upsell status once so App/TUI dialogs still fire, then stop instead of waiting. Free-tier API errors also persist the Go upsell message instead of a generic rate-limit string. Ordinary short-window 429s still retry.

How did you verify your code works?

• bun test test/session/retry.test.ts test/provider/error.test.ts in packages/opencode (65 pass)
• bun typecheck in packages/opencode

Potential Duplicate Found:

• PR fix: restore Go signup prompts and stop free-tier retries #46994: fix: restore Go signup prompts and stop free-tier retries
  • fix: restore Go signup prompts and stop free-tier retries #46994

Why it might be related:
Both PRs address the same feature: stopping retries for Go and free-tier usage quota limits, and ensuring Go upsell prompts are shown to users. PR #46994 appears to be a previous attempt at this same fix. You should verify whether #46994 is already merged/closed or if this PR (#47339) is a revised/rebased version addressing the same issue.
