fix: request name reverts after renaming an open request panel

[slverma]

Description

Problem

If a request panel is open and you rename that request from the sidebar, sending (or saving) the request afterward silently restores the old name.

Root cause

SidebarProvider.renameRequest persists the new name to storage and updates the panel title via RequestEditorProvider.updatePanelTitle, but never notifies the already-open webview. The webview's React state keeps the stale name in its config object. Both "Send Request" and "Save" post that full config back to the extension host, which writes it straight to storage and the sidebar tree — so the stale name overwrites the rename.

Fix

updatePanelTitle now also posts a requestRenamed message to the webview. RequestContext.tsx handles it by updating config.name in state, keeping the webview in sync so subsequent saves carry the correct name.

Files changed

• src/providers/RequestEditorProvider.ts
• src/webview/request/RequestContext.tsx

Test plan

• npx tsc --noEmit passes
• Manual: open a request, rename it via the sidebar context menu, then click Send — confirm the name stays renamed in both the sidebar and the panel title
• Manual: rename, then click Save — confirm the name persists after reopening the panel
