ci(bonk): bump opencode to 1.4.11 to unblock OAI through cf-ai-gateway

[NathanDrake2406]

What

Bump opencode_version from 1.4.6 to 1.4.11 in both bonk.yml and bigbonk.yml. Model + variant unchanged (cloudflare-ai-gateway/openai/gpt-5.4, xhigh).

Why

Two stacked regressions in opencode have made bonk on OAI through cf-ai-gateway uniquely broken on this repo. #902 dodged one and reintroduced the other.

Current state (1.4.6 + gpt-5.4):

APIError: Unsupported parameter: 'max_tokens' is not supported with this model.
Use 'max_completion_tokens' instead.
URL: https://gateway.ai.cloudflare.com/v1/compat/chat/completions

Failing run after #902: https://github.com/cloudflare/vinext/actions/runs/24939826275

opencode 1.4.6 predates the cf-ai-gateway plugin's chat.params hook (anomalyco/opencode#22864, merged 2026-04-16, first release 1.4.7). The hook strips maxOutputTokens for OpenAI reasoning models so @ai-sdk/openai-compatible no longer emits the rejected max_tokens field. Without it, every gpt-5.x request through the unified gateway fails at the OAI edge.

Why not 1.14.x: ProviderInitError on 1.14.22 / 1.14.25 (#898, #900) is a separate regression in opencode's npm install path. The 1.14 major bump added loadOptions(dir) via @npmcli/config inside Npm.add. When that throws on a CI runner, it surfaces as InstallFailedError, gets re-wrapped at packages/opencode/src/provider/provider.ts:1522 as InitError({providerID}, {cause: e}), and the session error path drops the original cause when emitting NamedError.Unknown({message: err.message}). Result: bots see UnknownError: ProviderInitError with no actionable detail. Same issue hit workers-sdk, workerd, kumo, etc., which all pin 1.4.6 / 1.2.27 for that reason.

Why 1.4.11: last release on the 1.4 line. Has the chat.params max_tokens patch (1.4.7+). Pre-dates the 1.14.x loadOptions install regression. ai-gateway-provider@3.1.2 and the @ai-sdk/* pins are identical to 1.4.6, so the install path stays the same arborist.reify shape that works for workers-sdk + anthropic on 1.4.6. vinext is the only Cloudflare repo running OAI through cf-ai-gateway, which is why we need the gpt-5.x plugin patch and they don't.

Approach

• bonk.yml: opencode_version: 1.4.6 -> 1.4.11
• bigbonk.yml: opencode_version: 1.4.6 -> 1.4.11
• No model, variant, or env changes

Validation

Reproduced both failure modes locally with opencode 1.14.25 + cloudflare-ai-gateway/openai/gpt-5.4 + fake creds. Confirmed:

• 1.14.x: Npm.add short-circuits on a stale empty cache dir (one path) and loadOptions fails on fresh install (other path), both surface as silent ProviderInitError.
• 1.4.6 with gpt-5.4: install succeeds, request reaches OAI, OAI rejects max_tokens.
• 1.4.7+ adds the chat.params hook that drops maxOutputTokens for OAI reasoning models.

Will comment /bigbonk review on this PR before merging to confirm bots come back up. If 1.4.11 still throws ProviderInitError for any other reason, fall back to anthropic + 1.4.6 (matches workers-sdk known-good).

Risks / follow-ups

• 1.4 line is no longer maintained upstream. We should roll forward once loadOptions is fixed (no upstream issue tracking it yet, since it surfaces as the masked ProviderInitError).
• The cause-swallowing in opencode's session error path is a real diagnostic bug worth filing upstream.
