- The local data directory (tools, language servers, index caches) is resolved in one place, ide_host::data_dirs::local_data_dir
- The variable must be an absolute path; a missing directory is created, and an unwritable one exits with an error instead of falling back to the system default
- Config and log directories still follow the system
- Add docs/data-directories.md
