v0.39.0 - File Auto-Send & QQ C2C Fix

Features

• File Auto-Send: Agent saves files to attachments directory, system automatically detects and sends to user via snapshot mechanism. Supports images, audio, video, and documents (PDF/Word/Excel/PPT/ZIP).
• QQ C2C File Sending Fixed: Resolved 850026 error by using uploadMedia with sendMessage: true for images, and two-step upload+send for audio/video/documents.
• Discord Button Support: Added button interaction handling for Discord, enabling interactive cards.

Bug Fixes

• Response Sending Logic: Fixed skipMessage logic to use !!card instead of !!card || !!streamSession - ensures QQ/Discord properly receive final responses
• Telegram Streaming: Disabled as multiple sends with preview cause message chaos

Improvements

• Unified platform file save prompts across all channels
• QQ documents include original filename hint (QQ platform strips filenames)
