feat: warn on root version mismatch in dev

[stevenle]

Motivation

• Ensure the root dev startup alerts developers when the CLI runtime version of @blinkk/root differs from the version declared by the project so they can fix mismatched deps.
• Handle common monorepo patterns (e.g. workspace: and range prefixes) when comparing versions to avoid false positives.

Description

• Add a startup task invoked from dev() (runDevStartupTasks) that runs a version check on server start in packages/root/src/cli/dev.ts.
• Implement warnOnRootVersionMismatch which loads the CLI package version via createRequire and the project-declared @blinkk/root version via flattenPackageDepsFromMonorepo and loadPackageJson, then logs a console.warn when mismatched.
• Add normalizeRootVersion to strip workspace:, ~, ^, and wildcard * cases before comparing versions.

Testing

• No automated tests were run for this change (per repository instructions).
