Fixes a small bug introduced in #16750 — the `moveCursor` and `clearLine` calls were _themselves_ being intercepted, so `mid_line` was always true, and we'd just print newline after newline --- ### Please don't delete this checklist! Before submitting the PR, please make sure you do the following: - [x] It's really useful if your PR references an issue where it is discussed ahead of time. In many cases, features are absent for a reason. For large changes, please create an RFC: https://github.com/sveltejs/rfcs - [x] This message body should clearly illustrate what problems it solves. - [ ] Ideally, include a test that fails without this PR but passes with it. ### Tests - [x] Run the tests with `pnpm test` and lint the project with `pnpm lint` and `pnpm check` ### Changesets - [x] If your PR makes a change that should be noted in one or more packages' changelogs, generate a changeset by running `pnpm changeset` and following the prompts. Changesets that add features should be `minor` and those that fix bugs should be `patch`. Please prefix changeset messages with `feat:`, `fix:`, or `chore:`. ### Edits - [x] Please ensure that 'Allow edits from maintainers' is checked. PRs without this option may be closed.

If app code writes to stdout without a trailing newline during prerendering on a TTY, the next progress line lands on the same row and the update after that clears the row:
The write proxies now track whether the last chunk ended mid-line, and the progress line starts a fresh row instead:
