* fix(plugins): add base64 handling for []byte and remove raw=true Go's json.Marshal automatically base64-encodes []byte fields, but Rust's serde_json serializes Vec<u8> as a JSON array and Python's json.dumps raises TypeError on bytes. This fixes both directions of plugin communication by adding proper base64 encoding/decoding in generated client code. For Rust templates (client and capability): adds a base64_bytes serde helper module with #[serde(with = "base64_bytes")] on all Vec<u8> fields, and adds base64 as a dependency. For Python templates: wraps bytes params with base64.b64encode() and responses with base64.b64decode(). Also removes the raw=true binary framing protocol from all templates, the parser, and the Method type. The raw mechanism added complexity that is no longer needed once []byte works properly over JSON. * fix(plugins): update production code and tests for base64 migration Remove raw=true annotation from SubsonicAPI.CallRaw, delete all raw test fixtures, remove raw-related test cases from parser, generator, and integration tests, and add new test cases validating base64 handling for Rust and Python templates. * fix(plugins): update golden files and regenerate production code Update golden test fixtures for codec and comprehensive services to include base64 handling for []byte fields. Regenerate all production PDK code (Go, Rust, Python) and host wrappers to use standard JSON with base64-encoded byte fields instead of binary framing protocol. * refactor: remove base64 helper duplication from rust template Signed-off-by: Deluan <deluan@navidrome.org> * fix(plugins): add base64 dependency to capabilities' Cargo.toml Signed-off-by: Deluan <deluan@navidrome.org> --------- Signed-off-by: Deluan <deluan@navidrome.org>
