[YoungDan]

Patch release v1.3.2 — user-facing fixes merged since v1.3.1.

Changes since v1.3.1

• Fix install.sh rate-limit handling and EXIT trap exit code #59 / install.sh: 403 on releases/latest and EXIT trap makes a successful install exit 1 #53 — installer: handle GitHub API 403 rate limits and preserve EXIT trap exit code in install.sh
• fix(auth): fail fast on login without TTY in CI #60 / auth login hangs with no TTY; CI should fail fast without DESLICER_DEV_TOKEN #54 — auth: fail fast on auth login without a TTY in CI (no hang)
• fix(auth): honor log-format, redact secrets, and require usable CI identity #66 / --log-format json is ignored on most error and status paths #55 auth status exits 0 when CI OIDC env vars are missing #56 JSON status/logout can leak DESLICER_DEV_TOKEN on stderr #58 — auth: honor --log-format json, redact secrets in output, require usable CI identity
• fix: docs --open in CI and update --check GitHub rate limits #67 / docs --open hangs in CI by launching a browser #61 update --check fails on unauthenticated GitHub API 403 #63 — docs: skip --open in CI; update --check GitHub rate-limit fallback
