v0.0.95

• PNG Metadata Extraction:
  • Implemented OllamaChat::Utils::PNGMetadataExtractor to support
    extraction of characters, prompts, and workflows from tEXt chunks.
  • Added support for Automatic1111 Stable Diffusion WebUI parameters via
    parse_a1111_parameters.
  • Consolidated metadata extraction logic into a new parse_png method
    within OllamaChat::Parsing.
  • Introduced OllamaChat::Utils::UTF8Converter to ensure safe UTF-8
    encoding across the system.
• Tool Improvements:
  • Enhanced the roll_dice tool by adding a human-readable message field
    to its JSON output and increasing the result_display_timeout.
• Command Interface:
  • Overhauled help texts for numerous commands (including /model,
    /system, /tools, /session, /prompt, and /persona) using
    squiggly heredocs for better formatting and clarity.
• Stability & Logic:
  • Updated OllamaChat::InputContent#all_file_set to filter out directories
    and return a Set.
  • Improved session name validation in
    lib/ollama_chat/session_management.rb by replacing .nil? with
    .blank?.
  • Added io.rewind within an ensure block in the PNG extraction logic to
    prevent read errors.
