Greptile Overview

Greptile Summary

This PR upgrades BrowserOS from Chromium 142 to Chromium 145, updating all chromium_patches to maintain compatibility with the new upstream APIs.

Major changes:

• Updated Chromium version from 142.0.7444.49 to 145.0.7632.46
• Bumped BrowserOS version from 0.39.0.3 to 0.40.0.0
• Disabled series patches (ungoogled-chromium extensions-manifestv2 and all Windows-specific patches) that are incompatible with Chromium 145
• Added new apply force command for non-interactive patch application during upgrades, which uses git apply --reject to handle conflicts

API compatibility updates across all patches:

• Migrated from std::unique_ptr<std::string> to std::optional<std::string> for network response callbacks (SimpleURLLoader API change)
• Added base::JSON_PARSE_RFC flag to all base::JSONReader::Read() calls (new required parameter in Chromium 145)
• Updated CopyFromSurface() API to accept base::TimeDelta timeout parameter and return CopyFromSurfaceResult instead of direct SkBitmap
• Changed AXNode::bool_attributes from optional pointer to direct member access (accessibility API refactoring)
• Updated histogram enum values from range 1951-1975 to 1957-1981 due to upstream additions
• Migrated from BrowserList::GetInstance()->GetLastActive() to GetLastActiveBrowserWindowInterfaceWithAnyProfile() for browser window access

All changes are mechanical API updates required for Chromium 145 compatibility. The new apply force build tool improves the upgrade workflow by allowing patches to be applied non-interactively with automatic conflict detection.

Confidence Score: 5/5

• This PR is safe to merge - all changes are mechanical API updates required for Chromium 145 compatibility
• The changes are entirely focused on maintaining API compatibility with Chromium 145. All modifications are consistent, well-structured mechanical updates: pointer-to-optional conversions, JSON parsing flag additions, screenshot capture API updates, and histogram enum reindexing. The new apply force tool follows existing patterns and improves the upgrade workflow. No logic changes or risky refactoring detected.
• No files require special attention - all changes follow consistent upgrade patterns
