Summary by CodeRabbit

• Refactor
  • Updated output during the bundling process to be directed to the standard error stream for improved visibility of logs and messages.

[coderabbitai]

Walkthrough

The update imports the "os" package and sets the Writer field of the bundler.BundleContext struct to os.Stderr within the PreflightCheck function, ensuring that output or logs are directed to standard error during the bundling process. No other logic or public interfaces are changed.

Changes

File(s)	Change Summary
internal/deployer/deployer.go	Imported "os" and set BundleContext.Writer to os.Stderr in PreflightCheck.

Poem

A tweak in the code, so subtle and neat,
Now errors and logs to stderr retreat.
With "os" in the mix, the streams are aligned,
The bundler’s output, more easy to find.
A hop and a skip, the rabbit approves—
Code flows to stderr, as logic behooves!

5-5: LGTM! Import addition is correct.

The import of "os" package is properly placed and necessary for the os.Stderr usage below.

79-79: Good fix for deployment error output.

Setting the Writer field to os.Stderr is the appropriate solution for ensuring deployment errors are properly written out. This follows the best practice of directing error output to stderr rather than stdout.
