Shared types, gRPC protocol, and provider SDK for the Konveyor migration ecosystem.

This crate provides the canonical types and protocol definitions used by Konveyor-compatible migration tools:

• [incident] -- Incident types (Incident, Position, Location) representing matched violations in source code.
• [report] -- Analysis output types (RuleSet, Violation, Category) matching the Konveyor analyzer-lsp output format.
• [rule] -- Rule definition types (KonveyorRuleset, KonveyorRule, KonveyorCondition) for the YAML rule format kantra consumes.
• [fix] -- Fix strategy types (FixStrategyEntry, MappingEntry, FixConfidence) for the fix-strategies.json bridge between analyzers and fix engines.
• [grpc] -- (behind the grpc feature) Proto-generated gRPC types, the ergonomic Provider trait, and generic server functions.

Features

• grpc -- Enables the gRPC module with tonic/prost dependencies, the Provider trait, ProviderAdapter, and serve_tcp/serve_unix.
• generate-proto -- Re-generates proto code from provider.proto.
