PR Summary

Medium Risk
Touches core request URL/query construction and retry timing behavior, which could subtly change request URLs or backoff behavior in edge cases; other changes are release/docs/CI plumbing.

Overview
Bumps the SDK to v1.20.1 (manifest/package/version/changelog updates).

Fixes URL construction by preserving query parameters already present in a provided path and merging them with default and per-request query params; stringifyQuery is moved into a new internal utility (src/internal/utils/query.ts) and tests are updated to import it directly.

CI now skips OIDC token retrieval and artifact uploads on stl/* branches, and the mock server script pre-installs Prism and adds a bounded startup wait with clearer timeout failure output; contributing docs are updated accordingly.

• ✅ Fixed: Malformed Retry-After causes zero-backoff retry loop
  • Restored validation so malformed, non-positive, or excessively large Retry-After values fall back to exponential default backoff instead of sleeping with zero delay.

Malformed Retry-After causes zero-backoff retry loop

High Severity

The guard if (timeoutMillis === undefined) no longer protects against NaN or negative timeoutMillis values. When a Retry-After header contains a non-numeric, non-date string, Date.parse() returns NaN, making timeoutMillis NaN. Since NaN !== undefined, the default backoff is skipped and sleep(NaN) is called, which setTimeout treats as 0ms. Similarly, a past date produces a negative value, also treated as 0ms. Both cases cause immediate retries with zero backoff, potentially hammering the server in a tight loop.
