BeefTV v1.5.9

• Validate reference image dimensions, aspect ratios, file sizes and audio/video duration using each model's configured capabilities before submitting.
• Preserve supported reference counts, resolutions and durations instead of silently dropping media or downgrading requested settings.
• Support local and inline reference audio for BeefAPI and native Ark channels, while retaining provider-specific audio-only rules.
• Show actionable reference conversion and request-size errors in both canvas nodes and task history, with safe diagnostics and no unsafe unchanged retries.
