sebrandon1/yaml-to-readme

AI Summary: Users need a way to preview which YAML files will be processed by the summarization tool without actually invoking the LLM. This issue proposes adding a `--dry-run` flag that identifies and lists all relevant YAML files, distinguishes between new files that would be summarized and existing ones that would be skipped, and then exits without making any LLM calls.

AI Summary: This GitHub issue aims to add comprehensive test coverage for the `writeIndividualSummary()` function and the `--localcache` flag, both of which currently lack testing. The goal is to introduce integration tests to exercise the local cache behavior and unit tests for the function, validating cache directory creation, file contents, and path-separator-to-underscore conversion in filenames.

AI Summary: The project currently lacks a `.golangci.yml` configuration file, leading to inconsistent linting behavior across different environments and `golangci-lint` versions. This issue proposes adding such a file to standardize linting, enable more specific linters like `gofumpt` and `gosec`, and explicitly document the project's code quality standards. The task involves creating the file, configuring it with appropriate linters, and ensuring existing code passes the new checks.
