fix(ci): write real newline in version.ts during publish version sync

[willwashburn]

Problem

The Publish NPM Packages → Build & Version job fails at the "Build all packages" step with @relaycast/sdk#build erroring on TS1127 "Invalid character" (exit code 2).

Failing run

Root cause

The version-sync step runs a Node script inside a single-quoted heredoc (<<'NODE'), so the shell passes the body to node verbatim — no escape processing. The writeFileSync calls used \\n:

fs.writeFileSync(sdkVersionPath, '...as const;\\n');

Node received \\n, and in a JS string literal '\\n' is an escaped backslash followed by n — so the generated version.ts ended with a literal \n (backslash + letter n) instead of a newline:

export const SDK_VERSION = "2.0.1" as const;\n   ← literal backslash-n

tsc then hit the stray \ and threw "Invalid character", failing the build.

Fix

Changed \\n → \n for both the SDK and CLI version files. Inside the quoted heredoc, \n reaches Node as \n, which the JS string evaluates to a real newline.

Verification

• Reproduced the bug by simulating the exact heredoc write (literal \n before, clean trailing newline after the fix).
• npx turbo build passes all 9 packages.

Reviewed PR #156. The workflow change is correct: the embedded Node script now writes real trailing newlines to packages/sdk-typescript/src/version.ts and packages/cli/src/version.ts, instead of literal \n text. No additional code changes were needed.

Validated locally:

• Extracted embedded workflow Node script parses successfully.
• Isolated version-bump execution writes newline byte 0a for both SDK and CLI version files.
• Workflow YAML parses.
• npx turbo lint --concurrency=1 --force passed.
• npx turbo test --concurrency=1 --force passed.
• npx turbo build --concurrency=1 --force passed.

Initial parallel lint/test attempts hit local exit 137 resource kills, then passed when rerun serially. package-lock.json content is unchanged after install.
