Note

Medium Risk
Mostly a generated release/version bump, but it changes SDK type shapes (many GeneratedMetadata* fields become optional and new fields like bpm appear) and tweaks Pydantic dump behavior, which could affect serialization and downstream type expectations.

Overview
Releases 0.48.0 by bumping the package/version metadata (pyproject.toml, _version.py, release-please manifest) and updating CHANGELOG.md and OpenAPI spec pointers in .stats.yml.

Updates Pydantic compatibility helpers so model_dump() only forwards by_alias when explicitly set, and raises the minimum typing-extensions version.

Regenerates several chunk/metadata models to loosen required fields to Optional[...] (e.g., language/size/counts/dimensions/duration) and add new optional metadata like bpm, impacting the public response/type surface.

Tweaks CI push branch filters to run on most branches while still excluding internal preview/integrated branches (with a carve-out for codegen/stl/**).
