1.7.0

This release adds some extra keybinds for opening text area content in your pager/json pager/editor.
It also adds warning toast popups if these aren't defined or cannot be executed.

A couple of focus related issues with jump mode are also fixed.

---

• Add: extra bindings - ctrl+P (note the capital "P", that is ctrl+shift+p on your keyboard!) in a TextArea opens pager, ctrl+E opens editor. This is in addition to the existing f3 and f4 bindings.
• Add: warning toast if user attempts to open pager/editor but none are configured in the environment.
• Add: error toast if the user attempts to open pager/editor, but it fails to run due to an OSError.
• Fix: workaround jump mode styling issue (awaiting upcoming Textual fix).
• Fix: collection tree wouldn't be refocused if jump mode was dismissed.
