Hot-reload the orchestrator's on-disk plugin registry without a
restart. Routes to the reload_plugins Rust IPC method, gated by the
same authz the orchestrator enforces (admin role OR platform-signed
JWT) so a forbidden caller gets a canonical ForbiddenError envelope
instead of a raw IPC error passthrough. The response body is a
ReloadStats { loaded, added, removed, updated, errors } summary,
validated against ReloadResponseSchema before being returned to the
caller.
Tests cover: admin success (200 + envelope), user-without-platform
(403 before IPC), bridge unavailable (400), orchestrator -32003 →
ForbiddenError, other IPC errors → BadRequestError, malformed
orchestrator payloads → BadRequestError.
