v0.0.100

• UUID v7 Integration: Implemented a compatibility shim via
  OllamaChat::UUIDV7.generate that utilizes native SecureRandom.uuid_v7 for
  Ruby 3.3+ and a custom RFC 9562 compliant implementation for older versions.
• Document Parsing & Embeddings:
  • Added EPUB support using pandoc.
  • Enhanced retrieval precision by prepending source identifiers to document
    chunks in embed_source.
• Structured Logging: Implemented a JSON formatter in OllamaChat::Logging
  with structured context support, including separate capture of backtraces and
  tool execution details.
• Prompt Management Refactor:
  • Unified prompt API using a context: keyword argument across management
    methods.
  • Restructured configuration to nest prompts under prompt:, suggest:,
    and system: contexts.
  • Promoted /suggest to a top-level command and simplified the /system
    command.
• Conversation Grouping: Introduced group_uuid in OllamaChat::Message
  to enable conversation grouping, including a repair_group_uuids method for
  legacy data migration.
• Tool Enhancements:
  • read_file: Added support for line numbering and range extraction;
    now returns total line_count and file mtime.
  • patch_file: Refactored to support coordinate-based patching via an
    edits parameter, including overlap detection and freshness checks using
    mtime.
  • generate_password: Added base64url alphabet support and critical
    security warnings regarding secret generation.
• CLI & UX Improvements:
  • Refactored command help strings with emoji prefixes and a concise
    multi-line format.
  • Added a welcome message upon startup displaying the application version,
    connected server version, and URL.
  • Standardized prompt and persona creation with a source selection menu
    ([CLIPBOARD], [FILES], [EMPTY/MANUAL]).
• Application Flow:
  • Implemented OllamaChatQuitError for graceful shutdowns via
    exception-based control flow.
  • Added a [QUIT-APP] option to the session chooser after deletion.
• Internal Logic & Stability:
  • Optimized ps_read using IO.copy_stream.
  • Centralized Ollama chat request logging through a new call_ollama_chat
    wrapper.
  • Added error logging to all tool execution methods.
  • Fixed defensive handling for JSON.load results in model handling to
    prevent nil propagation.
  • Removed implicit fallbacks to the last assistant response in
    copy_to_clipboard and paste_into_editor.
