fix(auth): preserve login cancellation and error codes

[AmanVarshney01]

What changed

Interactive deployment now runs prisma auth login --json with TTY stdin and captures its structured result. Explicit denial and prompt cancellation are treated as cancellation. Real auth failures retain the Prisma CLI error code for troubleshooting and telemetry. No login output is parsed with regex or inferred from a generic exit code.

Reproduction

With an isolated auth file, the published Prisma CLI reports AUTH.LOGIN_DENIED for OAuth denial. Ctrl-C at its paste prompt currently reports CLI.INTERNAL_ERROR; prisma/prisma-cli#275 fixes that to CLI.PROMPT_CANCELLED (verified against a locally built CLI). Previously create-prisma discarded both codes by inheriting all child streams, so both became prisma_auth_command_failed.

Verification

Unit tests, typecheck, formatting checks, build, and Windows creation smoke pass. Depends on the CLI fix only for Ctrl-C classification; this PR independently preserves structured login failures.

Summary by CodeRabbit

• Bug Fixes
  • Authentication prompts now run interactively, allowing users to complete Prisma sign-in in the terminal.
  • Recognized sign-in denials, cancelled prompts, and interrupted login processes are treated as authentication cancellations; other errors continue to be reported as failures.
• Tests
  • Updated authentication tests to check structured Prisma errors and interactive terminal behavior.

Walkthrough

Interactive authentication now runs Prisma login through runPrismaJsonCommandEffect with inherited stdin and stderr, piped stdout, and no --no-interactive flag. Specified Prisma login and prompt errors, plus interrupted or cancelled child-process errors, map to authentication cancellation. Tests check the command options and the outcomes for structured CLI error codes.

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to 9f920

Interactive login cancellation remains handled. Restoring the interruption test would improve regression protection, but no actionable merge-blocking failure is established.

Restore the interruption test without a JSON envelope.

The current mock always returns a JSON envelope for login failures. Add a login case with empty stdout and childProcessFailure: "interrupted", then assert CreateCancellationError. This preserves coverage for the path where the command exits before emitting an envelope.
