Confirmed via extensive isolated reproduction (docker run, plain BuildKit
RUN step, and Node child_process.spawn -- all three succeed) that TLS and
the sentry-cli invocation itself are fine; GlitchTip's releases API
rejects the authenticated request with "CSRF check Failed" (403) even
with clean token auth and no cookies. That's a server-side GlitchTip
issue (separate Docker stack), not something fixable from this repo.
Keeping ca-certificates/SSL_CERT_FILE since they're correct regardless.
