fix(ux): remove duplicate error logging in feature downloads

[skevetter]

Summary

• Remove duplicate error logging in processOCIFeature and processDirectTarFeature where log.Errorf was called immediately before returning the same error to callers
• Demote to log.Debugf where the log message adds context beyond the error itself (e.g. featureId, OCI reference, destination path)
• Remove log calls entirely where the message duplicates the error content
• Also clean up the same pattern in downloadFeatureFromURL

Release Notes

• Chores
  • Adjusted logging verbosity during feature acquisition, downshifting error-level messages to debug level for improved clarity in normal operation scenarios.

📝 Walkthrough

Walkthrough

Reduces log severity levels for errors during feature acquisition flows in three functions: processOCIFeature, processDirectTarFeature, and downloadFeatureFromURL. Error handling and propagation remain unchanged; only logging levels are adjusted from error to debug or removed.

Changes

Cohort / File(s)	Summary
Feature Logging Downshift pkg/devcontainer/feature/features.go	Downgrades error-level logs to debug level for OCI reference parsing, image fetch, layer download, extraction failures, and tarball operations during feature acquisition. Removes one invalid-format error log entirely. Error handling and returns unchanged.
