feat: implement enhanced message controls with regenerate any message

Added comprehensive message control features for fine-grained conversation management:

Backend (Rust):
- Extended Message struct with 'pinned' and 'hidden' boolean fields
- Added delete_message_at_index() command for removing any message
- Added toggle_message_pin() command to mark important messages
- Added toggle_message_hidden() command to temporarily hide messages
- Added continue_message() command to append AI continuations
- Added regenerate_at_index() command to regenerate ANY message (not just last)

Frontend (JavaScript):
- Added delete, pin, hide buttons to all messages (user & assistant)
- Added continue button for assistant messages
- Updated regenerate to work on any message, not just the last one
- Implemented state persistence for pinned/hidden in chat history
- Added dynamic icon changes for hide/unhide states
- Integrated with token counter for real-time updates

UI/UX (CSS):
- Pinned messages: accent-colored left border with glow effect
- Hidden messages: 40% opacity with blur effect (70% on hover)
- Delete button: red hover warning (#ef4444)
- Active state indicators for pin/hide buttons
- Always-visible controls on hidden messages for quick access

Features:
- Delete any message with confirmation dialog
- Pin messages to always keep them in context
- Hide messages with visual blur (still in context but dimmed)
- Continue incomplete assistant responses
- Regenerate any assistant message (creates new swipe)
- All states persist in chat history JSON

This completes Phase 3.2 "Enhanced Message Controls" from the roadmap,
providing users with complete control over their conversation history.
