Pull request overview

This PR updates the examples/with-docker Docker build context exclusions so the example ignores additional modern config file naming formats and Compose file extensions, keeping production images leaner.

Changes:

• Broadened test file ignores from explicit *.test.{ts,tsx,js,jsx} / *.spec.{...} to *.test.* and *.spec.*, and added common test-runner config globs (Vitest/Jest/Cypress/Playwright).
• Expanded ignored Docker/Compose filenames to include compose.yml/.yaml and docker-compose*.yaml.
• Added ignores for newer tool config formats (e.g. eslint.config.*, prettier.config.*, stylelint.config.*) and some AI agent metadata paths.

AGENTS.md is already excluded by the earlier *.md pattern, so this entry is redundant. Consider removing it (or, if the intent is to keep some markdown files in the build context, narrow the *.md rule and then keep explicit entries like this).

Suggested change

AGENTS.md

Hm, even if it is redundant now, it would be nice to keep for future changes, and to signal that this file should be ignored
