v1.0.0-rc3-hotfix7

## 🥇 We're getting close! 🥇 

We're full steam ahead toward our 1.0 release soon! This release candidate brings a sneak peek at lots of upcoming changes.

This release will require a data wipe, because we restructured the SpacetimeDB directory structure.

Some highlights:
- Lots of performance improvements!
- Removed the `println!` and `eprintln` macros in favor of `log::info!` and `log::error!`
- Fix defining multiple tables on the same `struct` in Rust modules
- CLI
  - Fixed `spacetime energy balance` not working at all
  - The `spacetime dns` subcommand is now `spacetime rename`
  - When updating the `cli.toml` config file, comments and formatting are preserved
- C#
  - New C# index syntax
  - Reduce noisy C# compilation errors
  - Fixed a bug where C# modules would not build if .NET 9 was installed on the system
