allow access cloud session downloads

[volodymyr-narada]

Note

Medium Risk
Adds new API calls that return presigned download URLs for cloud-session files and changes cloud session shutdown timeout; incorrect backend responses/permissions could expose or break download access.

Overview
Adds SDK support to list files downloaded in a cloud browser session. CloudBrowserWindow and RemoteBrowserWindow now expose get_downloaded_files(), which fetches the session’s downloads and resolves each file’s presigned GET URL via new replay endpoints.

Also updates the cloud browser example to demonstrate retrieving downloaded files, removes stale TODOs in cloud init, and increases the stop-session request timeout from 10s to 40s.

Duplicate get_downloaded_files implementation across classes

Low Severity

get_downloaded_files is implemented separately on both RemoteBrowserWindow and CloudBrowserWindow, with identical logic (calling _get_cloud_browser_downloads with the same parameters). Both classes already expose a cloud_browser_session_id property, so a single implementation in BaseBrowserWindow using that property could consolidate the two, eliminating the duplicated logic and reducing the risk of future inconsistency.
