3f44b97b5f- For every process that is spawned (every new non-trivial goroutine such as http requests, queues or tasks) start a [execution tracer](https://pkg.go.dev/runtime/trace). This allows very precise diagnosis of how each individual process over a time period. - It's safe and [fast](https://go.dev/blog/execution-traces-2024#low-overhead-tracing) to be run in production, hence no setting to disable this. There's only noticable overhead when tracing is actually performed and not continuous. - Proper tracing support would mean the codebase would be full of `trace.WithRegion` and `trace.Log`, which feels premature for this patch as there's no real-world usage yet to indicate which places would need this the most. So far only Git commands and SQL queries receive somewhat proper tracing support given that these are used throughout the codebase. - Make git commands a new process type. - Add tracing to diagnosis zip file.
