Upgrade to rslog v2 broke Node.js 18 compatibility (missing engines update) #110

Problem

Since create-rstack@1.8.0, the package depends on rslog@2.x (via #101). However, rslog@2 requires Node.js ^20.19.0 || >=22.12.0 (uses styleText from node:util, introduced in Node.js v20.12).

create-rstack itself still declares engines: {} (no restriction), causing a confusing runtime error on Node.js 18:

SyntaxError: The requested module 'node:util' does not provide an export named 'styleText'

Steps to Reproduce

1. Use Node.js 18.x (e.g. v18.19.1)
2. Run pnpm create <any-rstack-based-scaffold>@latest
3. Error occurs immediately

Expected Behavior

Either:

• create-rstack should update its engines field to >=20 to match rslog@2's requirement, OR
• Provide a fallback for Node.js 18 users

Downstream Impact

This issue was reported in downstream scaffolds that depend on create-rstack^1.0.0 and auto-upgraded to 1.8.x:

• pnpm create vue-lynx@latest error on Node.js 18.19.1 Huxpro/vue-lynx#117

We've worked around it by bumping our own engines requirement (Huxpro/vue-lynx#118), but the root cause fix belongs here.
