feat(sidebar): adds debounce on sidebar search

[sachin-thakur-bruno]

Description

Debounces the collection sidebar search so the collection tree is filtered on a 300ms instead of on every keystroke.

Problem

Each keystroke re-ran doesCollectionHaveItemsMatchingSearchText for every collection, which flattens
that collection's entire item tree on every call, then re-filtered each item row beneath it.
On workspaces with large collections this makes typing in the sidebar search visibly laggy.

Fix

• Sidebar/Collections/index.js now derives useDebounce(searchText, 300) and passes that to <Collection /> while <CollectionSearch /> keeps receiving the immediate value, so the tree walk runs once per pause rather than per character.
• An empty query bypasses the debounce, so clearing the box restores the full list instantly instead of after the delay.
• useDebounce accepts { skipDebounce }; a matching value is returned and committed straight away and
  cancels anything in flight, so nothing stale is left queued behind a clear.
• added unit tests for useDebounce

Walkthrough

The useDebounce hook now supports immediate updates for selected values. The collections sidebar clears searches immediately and debounces non-empty search input for 300 ms.

Changes

Debounced collection search

Layer / File(s)	Summary
Debounce hook behavior packages/bruno-app/src/hooks/useDebounce/index.js, packages/bruno-app/src/hooks/useDebounce/index.spec.js	useDebounce accepts an optional skipDebounce predicate. Tests cover immediate values, delayed updates, timer resets, and cancellation during retyping.
Collection search integration packages/bruno-app/src/components/Sidebar/Collections/index.js	The sidebar trims search text and applies a 300 ms delay to non-empty searches. Empty searches update immediately, and collection filtering uses the debounced text.

- Around line 27-28: Update the useDebounce integration in the Collections
sidebar so clearing searchText synchronously resets debouncedSearchText,
preventing a prior settled query from filtering after the user clears and
quickly types a new query. Preserve normal debounced behavior for non-empty
input, and add a regression test covering clear-then-type within
SEARCH_DEBOUNCE_MS.
