Add hand-rolled JSON-RPC 2.0 implementation for MCP server transports. Module: crates/pdftract-cli/src/mcp/framing/ - Id enum with Number/String/Null variants preserving JSON type - Request, Response, Notification, ErrorObject structs - BatchMessage for batch request handling - Strict jsonrpc version validation (must be "2.0") - All 6 spec-defined error codes (-32700, -32600, -32601, -32602, -32603, -32099..-32000) - Constructor helpers for common patterns Acceptance criteria verified: - Round-trip serialization/deserialization - ID type preservation (number/string/null) - Parse error responses with null id - Method not found error construction - Notification detection (no id field) - Batch request handling - Rejection of invalid jsonrpc versions - Empty batch rejection 16 unit tests covering all spec requirements.
