docs(merge-queue): changelog for inline queue metrics drilldown and extension updates

[samgutentag]

Summary

Covers two merge-queue improvements from June 16:

1. Queue Metrics inline drilldown (trunk2 #4185): The Queue Metrics health chart drilldown now opens inline under the chart (matching how Testing Metrics works), instead of navigating to a separate page.

2. Browser extension hides "Unable to merge as stack" row (trunk2 #4208): The extension now hides GitHub's "Unable to merge as stack" merge-box section alongside the existing "Merging is blocked" and "Branch out of date" rows.

Changes:

• Added changelog/2026-06-17-merge-queue-metrics-and-extension-updates.mdx
• Updated docs.json nav to include the new entry in June 2026
• Updated merge-queue/browser-extensions.mdx to add the new row to the hide-rows table
• Updated merge-queue/changelog.mdx with the new June 17 entry
