v8.4.0

• Added Fish shell support for dip console shell integration: dip console | source
• Added --shell (-s) option to dip console / dip console inject to force the shell dialect (bash, zsh, fish); autodetected from $SHELL by default
• Fixed dip.yml schema validation crashing on the json gem 3.0+ (Ruby 3.5+): unknown keyword: quirks_mode
• Fixed shell integration (dip console) re-running dip on every cd, even within the same project — it now only reloads aliases when the resolved dip.yml actually changes
• Fixed dip console inject paying for full dip.yml schema validation on every shell reload; it now only reads the interaction command names
• Fixed shell integration aliasing interaction commands over shell builtins/keywords (e.g. an interaction named jobs silently shadowed the jobs builtin, which prompts like Starship call on every render); such names are now skipped with a warning instead
