docs(skills): platform skill's Complete Working Example prints the scaffolder's TypeScript range (#16763)

The `package.json` block in `skills/objectstack-platform/SKILL.md` is the
on-ramp an AI author copies for a new project. Its `@objectstack/*` ranges are
maintained with the release; its `typescript` range was not, and still taught
the value the scaffold emission policy retired in #16485.

Read at flight time from `SCAFFOLD_TYPESCRIPT_RANGE`
(`packages/cli/src/commands/init.ts`), which all three scaffolders emit from —
never copied from the card or a comment, since restating a decaying constant is
the defect this change closes.

Byte-neutral: the block stays complete and no other value in it moves.
