/**
 * Checks whether an input object is *likely* a JSON Schema 7 object
 * Limitations:
 * - Does NOT validate nested schemas (e.g., inside `properties`, `items`, `definitions`, etc.)
 * - Does NOT check for correct usage of combinators (`anyOf`, `allOf`, `oneOf`, `not`)
 * - Does NOT verify required/optional keyword relationships (e.g., `required` only valid for object type)
 * - Does NOT validate formats, patterns, or constraints (e.g., `pattern`, `minimum`, `maximum`, etc.)
 * - Accepts both `definitions` and `$defs` for tolerance, but does not enforce draft-07 strictness
 * - Only checks for presence of top-level schema keywords
 * This is not a perfect validator, and does not check nested properties or full JSON Schema 7 compliance
