[RAIT-09]

🔬 Preview Release (v0.9.0-preview.1)

⚠️ This is a preview release — Features are experimental and may change. Please report any issues!

This preview adds context usage tracking, file attachment support, agent update notifications, and dynamic session configuration.

🌟 New:

• 📊 Context Usage Indicator: See how much of the agent's context window you've used, displayed next to the send button. Color changes at 70%/80%/90% thresholds to warn you before hitting limits. (Feature Request: Context window usage indicator #113)
• 📎 File Attachments: Attach non-image files (text, code, PDFs, etc.) to your messages via paste or drag-and-drop. Files are sent as resource_link content and rendered in chat messages. (Support non-image file attachments via Resource Link #77)
• 🔔 Agent Update Notifications: The plugin now checks if your ACP adapter (claude-agent-acp, codex-acp) has a newer version available on npm, and shows a dismissible notification with the update command. Also detects deprecated packages (e.g., claude-code-acp) and prompts migration.
• 🎛️ Dynamic Session Config: Agents can now provide configuration options (mode, model, etc.) via the ACP configOptions API. Dropdowns appear automatically in the chat input when available.
• 💾 Remember Last Used Mode: The last used mode is now saved per agent and automatically restored on the next session. (Default "modes" #136)

🔧 Improvements:

• 📦 ACP SDK Update: Updated @agentclientprotocol/sdk to v0.14.1.

🐛 Fixes:

• 📜 Auto-Scroll Threshold: Increased threshold from 20px to 35px for more reliable scroll tracking.

🚀 Upgrade:

Update from v0.8.3 — no extra configuration required. New features activate automatically when supported by your agent.
