fix(polling): move spinner from stderr to stdout to prevent consola collision

[BYK]

The spinner animation (withProgress/poll/startSpinner in polling.ts) writes to stderr using \r\x1b[K + braille frames. Consola is also configured to write exclusively to stderr. When log.info() fires inside a withProgress callback — e.g. "Applied delta patch" during sentry cli upgrade — it appends directly after the spinner text on the same line:

⠹ Downloading 0.20.0-dev.1774273283...ℹ Applied delta patch (74.9 KB downloaded)

Fix

Move the spinner from process.stderr to process.stdout. Since consola writes to stderr and the spinner now writes to stdout, the two streams no longer collide.

Also adds isPlainOutput() suppression to both withProgress() and poll() so the spinner is hidden when stdout is piped or in plain-output mode, preventing ANSI escape codes from reaching pipe consumers.

Changes

• src/lib/polling.ts: Move all spinner writes from stderr → stdout, add isPlainOutput() guard
• test/commands/issue/utils.test.ts: Update two spinner tests to spy on stdout instead of stderr, set SENTRY_PLAIN_OUTPUT=0 to force rich output in non-TTY test env
