v0.0.85

• Added list and rename subcommands to the /collection command, allowing
  users to display available collections and rename them via the
  rename_collection method in lib/ollama_chat/dialog.rb.
  • Made the /collection command optional; running /collection without
    arguments now displays collection statistics by invoking the
    collection_stats method.
  • Updated the help text and README to reflect the new command options and
    usage.
  • Adjusted the regular expression and completion configuration for
    /collection to include the new list and rename subcommands.
  • Added a rename_collection helper in lib/ollama_chat/dialog.rb that
    prompts the user for a new name and renames the current collection.
  • Updated tests to accommodate the new /collection command options,
    collection handling, and the renamed collection functionality.
• Introduced progress feedback in lib/ollama_chat/input_content.rb’s
  provide_file_set_content method, showing count/total during batch
  processing or just count in interactive mode.
• Optimized persona loading logic: the default persona is now skipped if the
  conversation already contains messages, while still falling back to
  command‑line options for new conversations.
• Fixed the warning condition in OllamaChat::FollowChat by correcting the
  success check logic.
