sebrandon1/yaml-to-readme

AI Summary: This issue proposes adding a `--dry-run` flag to the summarization tool. This flag would allow users to preview which YAML files would be processed, including a count of new and already summarized files, without actually invoking the LLM. The output would list the files that are slated for summarization, providing a valuable verification step before committing to potentially time-consuming processing.

AI Summary: This issue aims to improve test coverage by adding tests for the `--localcache` flag and the `writeIndividualSummary()` function. Currently, these parts of the codebase have no or very low test coverage, and the issue outlines specific acceptance criteria for validating cache directory creation, file content, and path conversion logic.

AI Summary: This issue proposes adding a `.golangci.yml` configuration file to the project's root directory. The goal is to standardize linting behavior across development and CI environments, enable more specific linters, and document code quality standards. The existing code must pass the new linting rules.
