Walkthrough

Bump Go toolchain (Dockerfile + go.mod) to 1.25; substantial dependency upgrades in go.mod (notably Firebase, gRPC, OpenTelemetry and related libs); small refactors replacing manual WaitGroup add/done with wg.Go(...); Firebase credentials call switched to option.WithAuthCredentialsJSON(...).

Changes

Cohort / File(s)	Summary
Build / Go version build/package/Dockerfile, go.mod	Updated build base image and Go directive to 1.25.0.
Dependencies go.mod	Bumped direct deps (e.g., firebase.google.com/go/v4, golang.org/x/crypto, google.golang.org/api) and reworked many indirects to newer OpenTelemetry, gRPC, protobuf, and Google Cloud modules.
WaitGroup refactor internal/sms-gateway/app.go, internal/sms-gateway/modules/messages/service.go, pkg/pubsub/memory.go	Replaced manual wg.Add(1) + go ... defer wg.Done() patterns with wg.Go(func(){ ... }) for background goroutines.
Firebase auth change internal/sms-gateway/modules/push/fcm/client.go	Switched Firebase app construction from option.WithCredentialsJSON([]byte(creds)) to option.WithAuthCredentialsJSON(option.ServiceAccount, []byte(creds)).

🚥 Pre-merge checks | ✅ 1 | ❌ 2

❌ Failed checks (2 warnings)

Check name	Status	Explanation	Resolution
Title check	⚠️ Warning	The title claims to upgrade grpc-go to 1.79.3, but the changes include upgrading Go from 1.24.3 to 1.25.0, updating multiple dependencies including Firebase, crypto, and Google API libraries, and refactoring goroutine lifecycle management across multiple files. The title is misleading about the primary scope of changes.	Update the title to reflect the actual main changes, such as 'Upgrade Go to 1.25.0 and update dependencies' or 'deps: upgrade Go to 1.25.0 and update Google Cloud dependencies'.
Docstring Coverage	⚠️ Warning	Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.
