Feature Request: Allow Ctrl + T to open new tabs inside the active folder

[pranavkiruthikmani]

Current Behavior:
Currently, when viewing a tab that is grouped inside a folder, creating a new tab using the keyboard shortcut Ctrl + T (or clicking the new tab button) spawns the new, blank tab outside of the active folder. Even when modifying core settings like browser.tabs.insertAfterCurrent to true, Zen Browser's vertical sidebar places the manual new tab at the bottom of the tab list or in the root workspace, requiring users to manually drag it back into the folder.

Desired Behavior:
When a user is focused on a tab that is inside a folder, pressing Ctrl + T should automatically spawn the new blank tab inside that same folder, directly adjacent to the active tab.

Why this is important:

Better Workflow: It removes the friction of constantly having to drag newly created tabs back into the folder you are actively working in.

Intuitive UI: If a user is working within a specific context (a folder), it is expected that new tasks (new tabs) created at that moment belong to that same context.

Consistency: Since there is already a workaround to keep child tabs (links opened from existing pages) inside folders using zen.folders.owned-tabs-in-folder, making blank manual tabs respect the folder boundary would make the tab management experience feel much more complete.

Thanks for all the hard work on the browser!

I would like to work on a PR for this, assuming nobody else has already started?
