Subject: [PATCH] chore: add Sentry breadcrumbs to subgraph proxy widget
 operations (#8996)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

Add Sentry breadcrumbs to subgraph proxy widget operations for better
observability of widget state changes.

## Changes

- **What**: Add `Sentry.addBreadcrumb()` calls with category
`'subgraph'` to `promoteWidget`, `demoteWidget`, and `pruneDisconnected`
in `proxyWidgetUtils.ts`

## Review Focus

Breadcrumbs are info-level and don't affect control flow. They log
widget name/node ID for promote/demote and removed count for prune.
