PR Summary

Medium Risk
Modifies URL construction, query serialization, and multipart file extraction/copying, which can affect request correctness across many endpoints. CI/release workflow changes are low risk but could change when checks/artifact uploads run.

Overview
Bumps the SDK to v0.4.0 (manifest, pyproject.toml, __version__, changelog) and updates the tracked OpenAPI spec metadata.

Improves request building and serialization: preserves query params embedded in endpoint URLs when merging with user params, adds a safe path_template() helper to percent-encode path placeholders and reject dot-segments, and implements indices array formatting for query strings.

Refactors multipart/file handling by replacing full-structure deepcopy_minimal with targeted deepcopy_with_paths, fixing multipart file array field-name emission via extract_files(..., array_format=...), and tightening a file-type error message; updates tests/docs accordingly. CI is adjusted to skip lint/build on metadata-only commits, tweak branch filters, avoid artifact upload on internal stl/* branches, and removes the release-doctor workflow/script.
