Walkthrough

The release adds generic warnings for options used without prerequisites. It documents option dependencies in the README, option definitions, and JSON schema. It adds dependency validation tests, centralizes paramCase, and updates the package version to 8.3.0.

Changes

Option dependency handling

Layer / File(s)	Summary
Dependency model and processing src/lib/utils.js, src/lib/options.js, cli.js	optionDependencies defines prerequisite options and clearing behavior. processOptions emits deduplicated warnings and clears unusable options. paramCase is shared by the CLI and option processing.
Dependency documentation and release metadata src/lib/option-definitions.js, README.md, html-minifier-next.schema.json, CHANGELOG.md, package.json	Option descriptions and documentation identify prerequisites, warning output, and excluded cache-size options. The package version is updated to 8.3.0.
Dependency and regression validation test/options.test.js, test/css+js.test.js, test/html.test.js, test/svg+mathml.test.js, test/cli.test.js	Tests cover dependency metadata, warning behavior, unavailable minifiers, schema consistency, cache handling, whitespace behavior, and updated test names.

Estimated code review effort: 3 (Moderate) | ~20 minutes

documentation heading to include a language identifier such as text on its
opening fence, resolving the MD040 warning while preserving the example content.

In `@src/lib/utils.js`:
- Around line 109-114: Reuse the existing paramCase function from
src/lib/utils.js in cli.js by importing it and removing cli.js’s duplicate local
implementation, while preserving the current CLI flag conversion behavior.
