Add a hash column to messages table computed from SHA-256(created_at + content)
to ensure message integrity. Existing messages get backfilled during migration.
All messages now show copy and permalink buttons on hover, with hash-based
URL fragments that auto-scroll and highlight the target message.

Add user profile page with custom avatar upload (crop/resize to 256px),
avatar display throughout the app, and MD5-based Gravatar fallback.
Add image paste/attach support in chat with vision model detection via
OpenRouter API. Images can be pasted from clipboard or selected via file
picker, uploaded to the server, and sent alongside messages. The AI
receives images as base64 data URLs for multimodal models. Models with
vision support are indicated with a badge in the model picker.
