chore: polish open source readiness

[afurm]

Summary

• prepare v0.1.1 with a changelog and refreshed package metadata
• remove the README Release Automation section and replace it with a compact changelog link
• make Node 24 the contributor, CI, and release-workflow default while keeping >=22.14.0 as the package support floor
• fix the TypeScript badge, add .node-version, and move README-only preview art out of runtime public/ assets
• update small dependency patches for React, React DOM, shadcn, and typebox

GitHub-side updates already applied

• disabled Wiki
• enabled delete-branch-on-merge
• enabled auto-merge support
• enabled Dependabot security updates
• added the missing setup label
• seeded public issues docs: add Windows and WSL2 setup notes #27, chore: add a package-size check to release validation #28, docs: add a maintainer release checklist #29, and test: smoke test the packaged CLI on another platform #30

Verification

• npm audit
• npm run typecheck
• npm test
• npm run build
• npm pack --dry-run --json
• npm outdated --json reports {}

Package dry run reports draftmora@0.1.1, packed size 587938 bytes, with the README preview image excluded from runtime package contents.

Follow-up after Node default adjustment:

• git diff --check
• npm run typecheck
• npm test
