This splits indexing into two phases:
* preindex (where only pages, space lua, space styles are indexed)
* index (where everything else is indexed)
The goal is to get to more-or-less operational state quicker this way,
because probably most functionality can already be enabled after the
pre-index phase.
* Don't require auth for .ping
* Finally introducing loggers
* Remove file list caching from disk_space_primitives
I don't think this is required anymore with the sync model
* Simplification of space primitives and more tests
* More reliable online status
* Add .zed settings
* Remove selfUpdate argument from `writeFile` no longer used
- Add `sync` config schema and document sync options
- Move sync config handling to client boot logic
- Move BootConfig type to ui_types.ts
- Remove sync env vars from server
- Update documentation for sync and architecture
* Improve sync logic and proxy routing for full sync state
* Add BoxProxy for late-bound client and improve Lua boot
- Add isMobile syscall for editor
* Add concurrency to sync process and log indexing duration
* Better service worker lifecycle management
