chore: drop a stray launch entry and format migrate.ts

An over-broad `git add -A` in the previous commit swept a local dev-server
entry for an unrelated application into .claude/launch.json. It pointed at a
path outside this repository and was not Prettier-formatted, so it failed
format:check. Restored to the version on main.

Also runs Prettier over migrate.ts, which the dead-code removal left unformatted.
