Move BuiltinPlugin into ocs_plugin_api (host feature) so out-of-tree crates can implement it, and add export_plugin! to emit the two C symbols a cdylib exposes: ocs_plugin_api_version (checked first, so an ABI-incompatible build never runs) and ocs_plugin_register -> boxed BuiltinPlugin. The host loads every compatible package from the plugins folder at startup via libloading (desktop only), keeps the library resident for the session, and merges its ribbon tab + command dispatch into the same paths as built-ins (honouring enable/disable). The Plugin Manager shows external packages with a Loaded / incompatible status. Approach B: the plugin hands back a boxed trait object, assuming a matching toolchain + ocs_plugin_api version (the version symbol enforces the latter). crates/ocs_example_plugin is the reference cdylib. Part of the #100 extensibility epic (phase 2). Co-Authored-By: Claude Opus 4.8 <[email protected]>
