v1.58.12

[1.58.12] — 2026-05-20

fix(ux): M-7 — cost hint now tracks the active provider (OpenRouter no longer falls through to a fabricated number). UI.providerCostHint() already routed via /api/status/providers so the line was provider-aware in spirit, but the per-provider maps in public/js/api.js only listed anthropic/gemini/openai/qwen. With v1.57.0's 5th provider live, OpenRouter fell through to the generic 0.03 fallback and rendered the literal openrouter (lowercase) as the provider name — both wrong. Per the fix-prompt's intent ("be honest, never quote a fixed number that might be wrong"), the EST map now lists openrouter: null (router picks the underlying model — cost varies per request), and the render path branches on null to emit a localized cost varies (router picks) instead of a fabricated ~$0.03/eval. NAME map adds openrouter: 'OpenRouter' so the user-visible name matches the docs. New i18n key cost.varies added across all 8 locales (cost varies (router picks) / coste variable (lo elige el router) / coste variable / etc.). 907 → 908 unit (tests/qa-report-fixes.test.mjs asserts EST openrouter: null, NAME openrouter: 'OpenRouter', the === null branch + t('cost.varies', …) call site, and 8-locale i18n parity). (M-7)
