fix: release package with CI (#570)

<!-- greptile_comment -->

<h2>Greptile Overview</h2>

Updated On: 2025-10-12 11:40:19 UTC

<h3>Summary</h3>

This PR fixes the NPM package release by suppressing verbose logs when
the validator is launched through the TypeScript wrapper. It sets
`RUST_LOG=quiet` in the NPM wrapper, and updates the Rust code to handle
this special value by printing directly to stdout instead of through the
logger.

**Major changes:**
- NPM wrapper now sets `RUST_LOG=quiet` when spawning the validator
- Rust `print_info` function now checks for `RUST_LOG=quiet` to decide
between `println!()` and `info!()`
- Added `setup-solana` action to CI workflow for wrapper package
publishing

**Issues found:**
- Incorrect path reference in workflow file that will cause CI failure

<h3>Confidence Score: 2/5</h3>

- This PR has a critical CI path error that will prevent the release
workflow from running successfully
- The logic changes for log suppression are correct and
well-implemented, but the workflow file has an incorrect path reference
(`./magicblock-validator/.github/actions/setup-solana` instead of
`./.github/actions/setup-solana`) that will cause the CI job to fail
- `.github/workflows/publish-packages.yml` needs the path corrected
before merging

<h3>Important Files Changed</h3>



File Analysis



| Filename | Score | Overview |
|----------|-------|----------|
| .github/packages/npm-package/ephemeralValidator.ts | 5/5 | Sets
`RUST_LOG=quiet` when spawning ephemeral-validator to suppress logs from
the TypeScript wrapper |
| .github/workflows/publish-packages.yml | 4/5 | Adds setup-solana
action to publish-wrapper-npm-package job, likely needed for package
build or validation |
| magicblock-validator/src/main.rs | 5/5 | Improves `print_info` logic
to support `RUST_LOG=quiet` for suppressing startup messages when called
from NPM package |

## Summary by CodeRabbit

- New Features
- Quieter default output: when logging is unset or set to “quiet,”
messages print plainly; otherwise, structured logging is used.
- Refactor
- Standardized log handling based on logging level for more predictable
console output.
- Chores
- Updated package publishing workflow to set up the Solana environment
prior to publishing the NPM package, improving reliability.
