chore(deps): move packages to TypeScript 6.0.3

Raises the typescript devDependency across the workspace, bumps package
versions, re-adds ignoreDeprecations, and repoints the @wrnexus registry.

These were pre-existing working-tree changes, committed as-is rather than
authored here. The .npmrc change redirects @wrnexus publishes from
registry.npmjs.org to registry.workroot.in — confirm that is intended
before publishing from this branch.
