BE-838: Restore Atlas package startup after CLI gating

[kostandinang]

🌟 What is the purpose of this PR?

Restore the Atlas package's start script after the Atlas binary was gated behind the cli feature. Without this, callers such as benchmark setup fail before Atlas starts, including the base comparison for #9585.

• Nothing

🔍 What does this change?

• Passes --features cli when the @rust/hash-graph-atlas start script invokes Cargo.

🏗️ Agent notes

The Atlas binary declares required-features = ["cli"]. The package script omitted that feature, so Cargo exited with target requires the features: cli and the benchmark harness later reported a healthcheck timeout.

Pre-Merge Checklist 🚀

🚢 Has this modified a publishable library?

This PR:

• does not modify any publishable blocks or libraries, or modifications do not need publishing

📜 Does this require a change to the docs?

The changes in this PR:

• are internal and do not require a docs change

🕸️ Does this require a change to the Turbo Graph?

The changes in this PR:

• do not affect the execution graph

⚠️ Known issues

None.

🐾 Next steps

Rerun the benchmark check on #9585 after this reaches main so its baseline checkout includes the repaired script.

🛡 What tests cover this?

• Invoked the package start script with --help; Cargo built and ran the Atlas CLI successfully.
• Pre-commit checks passed, including package formatting and task-dependency validation.

❓ How to test this?

1. Run mise exec -- yarn workspace @rust/hash-graph-atlas start --help.
2. Confirm Cargo builds the Atlas binary and prints its command-line help instead of reporting a missing cli feature.

📹 Demo

Not applicable; this repairs an internal start command.

@indietyp This issue was created while fixing #9585’s checks.

Cause:

• FE-1630: Optimize and measure the Brunch Voice relay #9585’s benchmark baseline invoked Atlas from main.
• Atlas’s binary requires the cli feature.
• ts package start script omitted --features cli, causing startup failure and a health-check timeout.
• Because FE-1630: Optimize and measure the Brunch Voice relay #9585 cannot repair its own baseline checkout, a separate one-line main PR was necessary.

Posting for confirmation: is this a relevant fix, or should the PR be closed?
