GitHub: SDK v0.0.68

• Provider errors forwarded through the Vercel AI Gateway now surface the real upstream message (e.g. "This model's maximum context length is 40960 tokens...") instead of a raw Zod issue dump, and opaque object errors no longer render as [object Object]
• fetchClineRecommendedModels now returns display-ready model names, resolved through the model catalog (including Vercel and OpenRouter id aliases) under a single shared timeout budget, so hosts no longer have to map ids to names themselves
• Cline free models now resolve their OpenRouter display names in the catalog
• The live catalog no longer drops the video input capability
• On Windows, PowerShell commands now travel over UTF-8 stdin instead of the command line, so non-ASCII commands survive the active code page and long commands are not capped by the Windows command-line limit — getShellInvocation() replaces the now-deprecated getShellArgs(), and a stdin write failure surfaces as a command error instead of hanging
• Fixed sessions rooted at the filesystem root (/) failing to run any command: basename("/") produced an empty workspace hint that schema validation rejected, so every command threw
• Exported the finish-reason and auth-error helpers used to describe agent errors
