patch

Fix stanza add monorepo turbo hard-failing on existing projects that lack a root .gitignore.

The append-to-file codemod gains an optional createIfMissing arg: when set and the target file is absent, it creates the file containing just the wrapped marker block instead of throwing. monorepo-turbo now passes createIfMissing: true for its .turbo/ .gitignore entry, so stanza add monorepo turbo works on a pre-existing project with no .gitignore (previously the whole add rolled back). The flag is additive and off by default — modules appending to peer-owned files (a Prisma schema, a framework's globals.css) keep the original "missing file is a peer-ordering bug" throw.
