feat: add "Duplicate as Tab" action to request tab menu

[brunorodmoreira]

Description

Adds a "Duplicate as Tab" option to the request tab right-click menu, mirroring Postman's "Duplicate Tab" idiom.

The existing Clone Request action requires a name in a modal and persists immediately to disk — well-suited for committing a copy. This new option duplicates the request into the collection's temp directory as a transient (unsaved) tab, pre-seeded with the source request's full state (including any unsaved draft changes), and opens it in a new tab. The user only commits to a name and folder if they later choose to save via the existing transient-save flow.

Reuses Bruno's existing transient-request infrastructure (temp directory + SaveTransientRequest modal); no new IPC, no schema changes.

Walkthrough

Adds a "Duplicate as Tab" menu action in RequestTab that dispatches a new Redux thunk, cloneItemAsTransient, to create a collision-free transient request file in the collection temp dir and enqueue OPEN_REQUEST; the UI shows a toast on errors.

Changes

Duplicate as Tab Feature

Layer / File(s)	Summary
Redux Thunk Implementation packages/bruno-app/src/providers/ReduxStore/slices/collections/actions.js	New cloneItemAsTransient thunk validates collection/temp directory existence, forbids folder duplication, locates the target item, generates a unique transient filename, transforms request payload, persists it via IPC (renderer:new-request), and enqueues an OPEN_REQUEST task.
RequestTab Menu Integration packages/bruno-app/src/components/RequestTabs/RequestTab/index.js	Imports cloneItemAsTransient and isItemARequest, derives isRequestTab from focused item, adds handleDuplicateAsTab that dispatches the thunk and surfaces errors via toast.error, inserts a "Duplicate as Tab" menu item (disabled when not a request), and updates the useMemo dependency array.

Poem

Duplicate a tab with nimble art,
A transient twin to play a part,
Click the menu, clone and go,
If it fails, a toast will show,
New tab opens — quick workflow.

In `@packages/bruno-app/src/components/RequestTabs/RequestTab/index.js`:
- Around line 697-701: The duplicate handler handleDuplicateAsTab uses
currentTabItem.uid without guarding against a briefly missing currentTabItem,
which can throw; update handleDuplicateAsTab to first verify currentTabItem and
currentTabItem.uid (and optionally collection.uid) exist, return early or show a
user-friendly toast if missing, and only then call
dispatch(cloneItemAsTransient(currentTabItem.uid, collection.uid)). Ensure error
handling for the dispatch remains (toast.error on catch) so the flow is safe if
state desyncs.

Pull request overview

Adds a new “Duplicate as Tab” option to the request tab context menu, enabling users to duplicate the currently opened request into the collection’s transient (temp-directory) request space and open it as a new unsaved tab—similar to Postman’s “Duplicate Tab” workflow.

Changes:

• Added a new collections thunk action (cloneItemAsTransient) that clones an existing request into the collection’s transient directory and queues it to open as a non-preview tab.
• Added a “Duplicate as Tab” menu item to the request tab right-click menu, with basic enable/disable logic based on tab type.
