`every([])` Returns `true` (Vacuous Truth)

[Hrdtr]

Describe the feature

// v1.x: every([]) → false
// v2.0: every([]) → true (matches Array.prototype.every semantics)

Rationale

JavaScript's [].every(fn) returns true. The v1.x behavior was non-standard and
asymmetric with none([]) → true.

Migration

Use $expr with length check if you need to deny empty arrays:

{ items: { length: ['gt', 0], $expr: ['every', { status: ['eq', 'active'] }] } }

Implementation Tasks

• Remove (value as any[]).length === 0 early return in every handler
• Update tests
• Document in migration guide
