feat(0): add useRules composable with Zod/Yup adapters

[johnleider]

Summary

• Adds useRules plugin to @vuetify/v0 providing alias-based form validation rules with token registry message storage and useLocale integration
• Adds @vuetify/v0/rules/adapters/zod and @vuetify/v0/rules/adapters/yup sub-path exports for zero-dependency integration with Zod and Yup validation schemas
• Adds full documentation at composables/plugins/use-rules.md including useLocale integration guide
• Fixes knip.json to explicitly list sub-path adapter files as entry points

New API

useRules plugin

import { createRulesPlugin, useRules } from '@vuetify/v0'

const app = createApp(App)
app.use(createRulesPlugin({
  aliases: {
    required: v => !!v || 'Required',
    email: v => /^.+@.+\..+$/.test(String(v)) || 'Invalid email',
  },
}))

// In component:
const rules = useRules()
const resolved = rules.resolve(['required', ['minLength', 8]])

Zod adapter

import { toRule } from '@vuetify/v0/rules/adapters/zod'
import { z } from 'zod'

const email = toRule(z.string().email('Must be a valid email'))
// Returns a FormValidationRule — no zod runtime in bundle for users who don't import

Yup adapter

import { toRule } from '@vuetify/v0/rules/adapters/yup'
import * as yup from 'yup'

const minAge = toRule(yup.number().min(18, 'Must be 18 or older'))

Integration with createForm

const form = createForm({ rules: createRules() })
const email = form.register({
  id: 'email',
  value: '',
  rules: ['required', toZodRule(z.string().email())],
})

Test plan

• useRules composable: 66 tests covering all 11 built-in aliases, resolve(), custom aliases, locale fallback, Trinity pattern
• All 2884 existing tests still pass
• Lint, typecheck, knip, sherif all pass

I think it's might be better to support https://standardschema.dev/, and get broader validation libs support: Zod, Valibot, ArkType, and more
