What

billing top-up is gone. The command is billing add-credits only (HeyGen's name, add-on credits); top-up is now an unknown action and gets the usual error, "Use billing subscribe or billing add-credits." No alias, no notice. A search of packages/cli, skills and docs (changelog history aside) finds no other top-up.

How

One line in billing.ts (the top-up to add-credits mapping) is deleted.

Tests

billing.test.ts: add-credits opens the credits page; top-up is refused with the error above and opens nothing.
Fails without the fix: with the mapping back, the top-up test fails (it would open the credits page instead of refusing).
The billing tests ran on a remote box (run in flight when this was pushed; result in a comment).

Size

A one-line removal Miguel asked for, kept separate so it can land before the next release.

• billing.ts: removing the alias line means top-up now goes down the unknown-action path. It prints "Use billing subscribe or billing add-credits." and calls failCommand() before anything is read or opened. The positional help and the description already list only subscribe | add-credits.
• I found no other top-up in packages/cli, skills or docs. The one hit in packages/core is the unrelated font top-up.
• The fails-without-the-fix claim holds. I ran it locally: billing.test.ts passes 5/5 at head. With the old mapping restored, "refuses the old name top-up like any unknown action, naming the valid ones" fails and the other 4 pass.
• CI was still running when I reviewed (CI, CodeQL, Windows render). The checks that had finished were green.

Remote run on the first layout of this change: billing.test.ts 5 passed. With the mapping put back, the refusal test fails (1 failed, 4 passed), so it catches the alias. The pushed head only re-indents the test body for the formatter; CI's format check covers that.
