Instructions for building SpacetimeDB Standalone + spacetimedb-cli from master, put this into the README

[cloutiertyler]

jdetter:

Essentially the instructions are:

cargo build --release -p spacetimedb-cli -p spacetimedb-update -p spacetimedb-standalone

Then users need to put binaries in the right spots. Script that I shared with a user today for this:

# the update command becomes the "spacetime" binary
mkdir -p ~/.local/bin
mv spacetimedb-update-x86_64-unknown-linux-gnu ~/.local/bin/spacetime

# extract the tarball and install
tar xf spacetime-aarch64-unknown-linux-gnu.tar.gz
mkdir -p ~/.local/share/spacetime/bin/1.0.0
mv spacetimedb-cli ~/.local/share/spacetime/bin/1.0.0
mv spacetimedb-standalone ~/.local/share/spacetime/bin/1.0.0

# Set the current version
spacetime version use 1.0.0

Caused by:
  feature `edition2024` is required

  The package requires the Cargo feature called `edition2024`, but that feature is not stabilized in this version of Cargo (1.83.0 (5ffbef321 2024-10-29)).
  Consider trying a newer version of Cargo (this may require the nightly release).
  See https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#edition-2024 for more information about the status of this feature.

@syonfox rustup update and then try again, you just need the latest version of cargo
