fix: use maturin build --release for dynamo source installs

[ishandhanani]

Debug builds (maturin build without --release) produce binaries that are ~40% slower than release-optimized pip wheels, causing misleading benchmark comparisons. Also removes -C target-cpu=native which caused a separate release-mode bug with /v1/completions streaming.

Walkthrough

Modified the Dynamo source-install command in DynamoConfig.get_install_commands() by removing the -C target-cpu=native CPU-specific flag from RUSTFLAGS while retaining --cfg tokio_unstable, and changed the maturin invocation from a default build to an explicit release build.

Poem

🐰 A rabbit hops through build flags with care,
Removing native CPU, keeping configs fair,
Release builds faster, no more default way,
Tokio whispers remain to save the day! 🚀
