[log] Add debug logging to cmd/tracing_helpers.go

[github-actions]

Summary

Adds 5 debug logging calls to internal/cmd/tracing_helpers.go using the existing debugLog variable from the cmd package (logger.New("cmd:root")).

Changes

File: internal/cmd/tracing_helpers.go

initTracingProviderWithFallback

• Log before attempting tracing provider initialization
• Log on successful initialization
• Log on failure with fallback to no-op provider (includes error detail)

shutdownTracingProviderWithTimeout

• Log before shutdown attempt
• Log on successful shutdown
• Log on shutdown error (includes error detail)

Why This Matters

These functions handle critical startup and shutdown lifecycle events for OpenTelemetry tracing. With DEBUG=cmd:*, developers can now observe:

• When tracing is being initialized and whether it succeeds
• When the fallback no-op provider is triggered (indicating a misconfigured OTLP endpoint)
• When tracing shuts down cleanly vs. with errors

Validation

• go build ./... ✅
• go vet ./internal/cmd/... ✅
• go test ./internal/cmd/... ✅ (all tests pass)

Quality Checklist

• Exactly 1 file modified
• No test files modified
• Reuses existing debugLog logger (no new logger declaration needed)
• Logger naming follows pkg:filename convention (cmd:root)
• Logger arguments have no side effects
• Logging messages are meaningful and helpful
• No duplicate logging with existing logs
• Changes validated with build and tests
