Function validate_plugin_config

crates/core/src/plugin.rs:866–901

Validates a plugin configuration document. This is a pure validation pass. It does not mutate the active runtime configuration. # Parameters - `config`: Plugin configuration to validate. # Returns A [`ConfigReport`] describing warnings and errors discovered during validation. # Notes Validation checks host policy, plugin multiplicity rules, unknown component kinds, and plugin-provided validati
