v0.0.76

• Added client: and current_directory: keys to runtime info values in the
  chat module.
• Implemented a #client method that returns the program name and current
  version.
• Introduced a location_description? helper for optional location
  description.
• Simplified MessageList#to_ary to return a duplicate of the internal array,
  removing automatic system prompt and location injection.
• Updated default configuration placeholders for %{client} and
  %{current_directory}.
• Adjusted web‑searching logic to use location_description? instead of
  deprecated methods.
• Standardized JSON output formatting across tools: aligned keys, added spaces
  after commas, and added trailing commas.
• Added trailing commas to JSON objects for consistency and easier future
  edits.
• Standardized error field formatting with spaces after the colon and trailing
  commas.
• Added a disable_content_parsing helper that sets @parse_content to
  false.
• Refactored command handlers to call disable_content_parsing instead of
  directly assigning to @parse_content.
• Updated persona setup logic so that a returned persona result triggers
  disable_content_parsing; otherwise parsing is enabled with
  enable_command_completion.
• Improved clean flow by capturing the return value of clean and setting
  @parse_content = true when a persona profile is returned.
• Replaced the old @persona_setup flag with @default_persona, defaulting to
  :none after setup.
• Added a reload_default_persona method that prompts for confirmation before
  reloading the default persona file.
• Modified /clear command handling to use the returned value from clean and
  proceed only when nothing is returned.
• Added gems to the code indexer configuration for navigation tags:
  all_images, const_conf, context_spook, csv, fileutils, gem_hadar,
  infobar, irb, kramdown, and kramdown-parser-gfm.
