fix(client): mark some request bodies as optional
Note that we still want to run tests, as these depend on the metadata.
Pin all GitHub Actions referenced in generated workflows (both
first-party `actions/*` and third-party) to immutable commit SHAs.
Updating pinned actions is now a deliberate codegen-side bump rather
than implicit on every workflow run.

P1 Public Response Imports Removed

The 4.1.0 package removes the documented VoiceCreateResponse, VoiceRetrieveResponse, and VoiceUpdateResponse exports. Applications importing these names from brainbase.types.workers.deployments will fail at startup after a minor-version upgrade; compatibility aliases to VoiceDeployment are needed for the 4.x line.

P1 Minor Release Drops Python 3.8

Changing requires-python from 3.8 to 3.9 makes this minor release unavailable to existing Python 3.8 installations. Keep the previous runtime floor for the 4.x line or make the compatibility break a major release.

P2 Overlapping File Paths Lose Data

When file-extraction paths share a dictionary key and one remaining path consists only of <array> markers, this branch pops the whole value before the later path can traverse it. A request schema with paths such as files[].file and files.extra can therefore omit the second field or fail extraction.
