PR Summary

Medium Risk
Touches core request building and URL/path handling (query param merging, endpoint path interpolation, query array serialization), which could affect how requests are formed across the SDK. CI gating changes are low risk but could change what runs on certain branches/commits.

Overview
Bumps the SDK to v0.4.0 (manifest/version files, changelog) and raises the minimum typing-extensions to >=4.14.

Improves request construction by preserving hardcoded query params already present in options.url when merging with user-provided params, and adds coverage for this behavior. Adds support for indices array serialization in the query/form stringifier.

Introduces path_template() for sanitized endpoint path interpolation (percent-encoding + rejecting ./.. path segments) and migrates models.retrieve to use it, with new unit tests. Updates pydantic compatibility to avoid passing by_alias unless explicitly set, and refactors a generated TypedDict to use PEP 728 extra_items.

CI is tweaked to adjust branch filters, skip lint/build on codegen metadata-only pushes, and avoid artifact uploads on internal stl/* branches; .gitignore adds .stdy.log, and test fixtures replace raw file contents with Example data.
