Auto-generated changelog update for BrowserOS Agent Extension v0.0.52.

[greptile-apps]

Greptile Summary

This auto-generated PR adds the first changelog entry for the BrowserOS Agent Extension, recording version v0.0.52 dated 2026-03-26 in a file that previously only contained a heading. The diff is purely documentation with no code changes. The entry description Initial release is potentially misleading for a package already at version v0.0.52; a clearer label would reduce reader confusion.

Confidence Score: 5/5

Documentation-only change with no code impact; safe to merge.

The change is a single-line documentation addition to a changelog file. There are no code, logic, or security concerns. The only open item is a P2 style suggestion about the entry description.

No files require special attention.

Comment:
**"Initial release" description is misleading for v0.0.52**

The description `Initial release` is typically reserved for the very first published version of a package (e.g., v0.0.1 or v1.0.0). Using it for v0.0.52 could confuse readers who assume it refers to the first version ever shipped, rather than the first version tracked in this changelog.

Consider using a more accurate description such as `First changelog entry` or `Initial tracked release`, or summarizing the actual changes in this version:

```suggestion
First changelog entry — prior versions were not tracked in this file.
```

How can I resolve this? If you propose a fix, please make it concise.
