feat(helpers/counter): add new thread-safe counter package

[madflojo]

This pull request introduces a new test-focused, thread-safe counter package (helpers/counter) to the repository, along with supporting configuration, documentation, and build system updates. The counter package is designed to help coordinate asynchronous tests and provides atomic operations and wait helpers. Additional changes ensure that the new module is properly integrated into CI, release, and build workflows.

New package addition:

• Added the new helpers/counter package, including implementation (counter.go), tests (counter_test.go), usage examples (counter_example_test.go), Makefile, and go.mod. The package provides atomic increment/decrement, direct value manipulation, and wait helpers for test coordination. [1] [2] [3] [4] [5]

Documentation updates:

• Updated README.md and testlazy.go to document the new counter package, including usage examples and a description in the package table. [1] [2] [3]

Release and build system integration:

• Updated release configuration files (.release-please-config.json, .release-please-manifest.json) to include helpers/counter for versioning and changelog generation, and added the module to the build/test/lint targets in the root Makefile. [1] [2] [3]

Continuous integration and dependency management:

• Added helpers/counter to Dependabot configuration for automated dependency updates and to GitHub Actions workflow for Go 1.24 compatibility and coverage reporting. [1] [2]

Formatting improvements:

• Enhanced formatting steps in the root and module-level Makefiles to use golines for line wrapping if available, improving code readability. [1] [2]
