//! Layer 7 application, infrastructure, telemetry, and industrial OT protocol field parsers.
//!
//! This module organizes the syntactic combinator parsers for all 50 Layer 7 protocols supported by
//! the FrameAssembly language, including core infrastructure services (`DNS`, `mDNS`, `DHCP`, `NTP`,
//! `PTP`), network management and telemetry (`SNMPv1`/`v2c`/`v3`, `RADIUS`, `TACACS+`, `Syslog`,
//! `NetFlow`, `IPFIX`, `sFlow`), web and RPC transport (`HTTP/1.1`, `HTTP/2`, `gRPC`, `WebSocket`,
//! `TLS`, `QUIC`), real-time media (`STUN`, `SIP`, `RTP`, `RTSP`), enterprise directory and storage
//! (`SMTP`, `IMAP`, `POP3`, `Kerberos`, `LDAP`, `SMB`, `NFS`, `SSH`, `Telnet`, `FTP`, `TFTP`),
//! data/IoT messaging (`Redis`, `Memcached`, `MySQL`, `PostgreSQL`, `MQTT`, `CoAP`, `AMQP`, `SSDP`,
//! `WHOIS`), and industrial SCADA/OT (`Modbus`, `BACnet`, `DNP3`, `S7comm`, `EtherNet/IP`, `OPC UA`).
