Added support for all v2/v3 character card fields in the character editor UI:
- Description (10-row textarea)
- Scenario
- Message Example
- Post-History Instructions
- Alternate Greetings (one per line)
- Tags (comma-separated)
- Creator
- Character Version
- Creator Notes
Updated frontend to load and save all fields, and backend update_character
command to accept all new parameters. This allows imported v3 character cards
to display their full details, especially the description field which contains
the main character information.

- Added read_png_text_chunks() function that manually parses PNG file structure
- Reads PNG chunks directly instead of relying on png crate's Info struct
- More reliable extraction of tEXt chunks with "chara" keyword
- Added debug logging (eprintln) to help diagnose import issues
- Updated read_character_card_from_png() to use manual parser as primary method
- Fixes "missing 'chara' chunk" error even when chunk exists in file
- Successfully imports both v2 and v3 character cards
- Added CharacterCardV3 struct to handle v3 format
- Created From<CharacterCardV3> for CharacterCardV2Data conversion
- Updated read_character_card_from_png() to detect and parse both v2 and v3 specs
- V3 cards have top-level fields + nested data object
- Maintains full backward compatibility with v2 cards
- Export still uses v2 format for maximum compatibility
- Expanded Character struct with all v2 spec fields (description, scenario, mes_example, post_history_instructions, alternate_greetings, character_book, tags, creator, character_version, creator_notes, extensions)
- Created CharacterCardV2 serialization structs following spec at github.com/malfoyslastname/character-card-spec-v2
- Implemented PNG metadata utilities:
* read_character_card_from_png() - extracts and decodes character data from PNG tEXt chunks
* write_character_card_to_png() - embeds character data into PNG files
* create_placeholder_png() - generates gradient placeholder images for avatarless characters
- Added Tauri commands:
* import_character_card - opens file picker, imports PNG with automatic name conflict handling
* export_character_card - exports character as v2 PNG card with embedded metadata
- Added Import/Export buttons to character settings UI
- Full backward compatibility with existing characters using serde defaults
- Added dependencies: png 0.17, base64 0.21, image 0.24
- Added swipe system to Message struct with backward compatibility
- Implemented swipe navigation UI with left/right arrows and counter
- Added generate_response_only and generate_response_stream commands

- Support PNG, JPG, JPEG, and WEBP formats
- Modal closes on overlay click or ESC key
- Add server-sent events (SSE) streaming support for real-time token display
- Implement progressive markdown rendering during streaming
- Add stream toggle in API settings (defaults to disabled for compatibility)
- Add visual streaming indicator with pulsing animation
- Graceful fallback to non-streaming mode when disabled
- Fix character saving bug (camelCase parameter naming)
Backend changes:
- New chat_stream command with SSE parsing
- Added futures and bytes dependencies
- Emit chat-token events progressively to frontend
