Test Coverage PR-3: Tests added in ./cmd subdir

[mohanmanikanta2299]

🛠️ Description

Summary

This PR is the 3rd part of the test coverage PRs intended to increase the test coverage of the entire repo from 55% to 80+%, fulfilling our coverage requirements.

Changes Made

• Implemented comprehensive table-driven tests for the cmd package.
• debug.go, dispatch.go, init.go, report.go, root.go, utils.go -- list of files in cmd package for which the test have been created/updated.
• Added validation for CLI command flags, ensuring default values and flag bindings are properly configured.
• Added strict assertions (assert.Equal, assert.Contains) and explicit error checking to validate function outputs and edge cases.
• Used require for critical initializations (like loggers and flag lookups) to prevent nil-pointer panics during test execution.

Testing

• Ran go test -v ./... (All tests passing)
• Ran go test -race ./... (No race conditions detected)
• Verified coverage metrics locally.

Pull request overview

This PR adds/expands table-driven tests in the cmd/ package to improve overall repository test coverage, focusing primarily on Cobra command wiring (flags/help/registration) and a few utility helpers.

Changes:

• Added new unit tests for core CLI commands (root, init, report, dispatch, debug) to validate flag defaults, help text, and command registration.
• Expanded cmd/utils_test.go to cover additional utility behaviors (GetVersion, table writer setup/rendering, stringArrayToRow).
• Added subprocess-based tests for init PreRun validation paths that call cobra.CheckErr (which exits).
