Faster JetBrains IDEs with shared indexes

JetBrains IDEs, such as IntelliJ IDEA, PyCharm, and GoLand, require indexing for features like code search, highlighting, refactoring, and code completion. However, this process can be time-consuming, especially for large projects or slow machines. Shared indexes can significantly reduce IDE load times by hosting pre-generated indexes for others to download. Generating shared indexes using a Docker container simplifies the process and allows for automation with cron/CI. Benchmarking results show significant improvements in loading speeds, particularly for large projects. JetBrains' remote development support also benefits from shared indexes, as they can be included in workspace images for faster onboarding and better reproducibility.
