Pull Request Overview

This PR lays the groundwork for Deno2 by updating core versioning and dependency management while replacing legacy argument parsing with a new CLI module. Key changes include:

• Bumping the package version to "2.0.0-pre.0" and updating related version references.
• Replacing Deno’s legacy flags module with a new CLI library and updating import paths accordingly.
• Updating workflow configurations and adding new tasks (check, lint, fmt) for local verification.

• The installation command still references dnit-v1.14.4 while the version in version.ts is updated to "2.0.0-pre.0". Please update the version reference in the README to ensure consistency.

deno install --global --allow-read --allow-write --allow-run -f --name dnit https://deno.land/x/dnit@dnit-v1.14.4/main.ts

launch.ts:118

• Verify that semver.satisfies accepts the parsed version objects returned by semver.parse() and semver.parseRange(), as this change may affect version comparison behavior.

return semver.satisfies(semver.parse(denoVersion), semver.parseRange(denoReqSemverRange))
