fix: align Go version to 1.24.0 across all CI workflows and fix Makefile

[Rayhan1967]

Description

This PR fixes inconsistencies in the CI/CD configuration and resolves the Makefile lint target execution issue.

Problem

1. Go Version Mismatch: The CI workflows were using Go 1.23.6 while go.mod specifies Go 1.24.0, causing potential compatibility issues during builds and tests.
2. Lint Target Failure: The make lint command fails with "golangci-lint: No such file or directory" because the installed binary is not in the PATH.

Solution

• Updated Go version to 1.24.0 in all CI workflow files to align with go.mod
• Fixed the Makefile lint target to use the explicit path $(HOME)/go/bin/golangci-lint

Files Changed

File	Change
.github/workflows/golangci-lint.yml	Go version: 1.23.6 → 1.24.0
.github/workflows/doc.yaml	Go version: 1.23.6 → 1.24.0 (2 occurrences)
Makefile	Added explicit path for golangci-lint binary

Verification

• ✅ Unit tests pass
• ✅ Lint passes
• ✅ Terraform format check passes

Why not upgrade all to 1.25 or 1.26?

Why not upgrade all to 1.25 or 1.26?

As you can see in the file changes, this PR only touches the CI workflows and Makefile. Upgrading to Go 1.26 would require to update go.mod and test all dependencies, which is better suited for a separate, dedicated PR.
