Restore `PluginDescriptor::encoding` to `std::vector<std::string>` so the embedded-manifest decoder accepts the array-shaped `encoding` that every bundled parser manifest ships (`parser_json`, `parser_protobuf`, `parser_data_tamer`, `parser_ros`). A previous refactor narrowed `encoding` to a single `std::string` and required it via `requiredString()`. As a result every parser was rejected at scan time with `plugin embedded manifest missing required string key: encoding` and no parser-backed data source could load. Changes: - `PluginDescriptor::encoding` is now `std::vector<std::string>`. - `decodeManifest` reads `encoding` via `readStringArray` and keeps the "non-empty for kMessageParser" requirement. - `PluginRuntimeCatalog::loadAndRegisterMessageParser` inserts every entry into `loaded.encodings` instead of pushing one string. - Mocks and docs updated to the array shape. - Unit test updated to compare against `std::vector<std::string>`. Testing: - `ctest --test-dir build -R plugin_catalog_test` passes. - pj_proto_app loads csv, json, protobuf, mcap, parser_ros and the ROS 2 subscriber after this fix; previously all parsers were ignored at boot.
The MessageParserLibraryTest.ManifestRoundTrip assertion still searched for the legacy "encoding":"json" substring. After the encoding-array fix the mock manifest serializes encoding as ["json"], so the assertion is updated accordingly.

Summary
Fix the embedded-manifest decoder so it reads
encodingas an array of strings.PluginDescriptor::encodingis nowstd::vector<std::string>(was a singlestd::string).decodeManifestreadsencodingviareadStringArrayand keeps the "non-empty forkMessageParser" requirement.PluginRuntimeCatalog::loadAndRegisterMessageParserinserts every entry intoloaded.encodingsinstead of pushing one string.std::vector<std::string>.Why
A previous refactor narrowed
encodingto a singlestd::stringand required it viarequiredString(). Every bundled parser manifest (parser_json,parser_protobuf,parser_data_tamer,parser_ros) shipsencodingas a JSON array, so every parser was rejected at scan time withplugin embedded manifest missing required string key: encodingand no parser-backed data source could load.This restores the array shape so multi-encoding parsers (e.g.
parser_rosadvertising bothros1andros2) work as designed.Testing
ctest --test-dir build -R plugin_catalog_testpasses (assertion updated).pj_proto_apploads csv, json, protobuf, mcap,parser_rosand the ROS 2 subscriber after this fix; before, all four parsers were ignored at boot.
