Unreleased

Initial v0.1 release. See DESIGN.md for the full plan.

Added

• Repository skeleton: pyproject.toml, Makefile, CI/docs/publish workflows,
  pre-commit config, src/tests/docs layout.
• Foundational pure-Python pieces:
  anymodbus._types (enums + small dataclasses),
  anymodbus.exceptions (full ModbusError tree + code_to_exception translator),
  anymodbus.crc (CRC-16/Modbus, 256-entry table),
  anymodbus.config (frozen dataclasses with validation).
• WordOrder and ByteOrder named enums for 32-bit value layout, with
  defaults matching the Modbus Application Protocol spec example
  (high-word-first, big-endian within word).
• Bus (half-duplex single-master client) and per-slave Slave handle, with
  open_modbus_rtu(...) convenience opener over anyserial.
• Length-aware RTU Framer with timing-gap fallback for unknown function codes
  and tx-side 3.5-character pre-tx idle gap.
• PDU encode/decode for the v0.1 function code set (FC 1–6, 15, 16) and
  decoders for 32-bit float / int values across two registers.
• Capability model (SUPPORTED/UNSUPPORTED/UNKNOWN) populated from probe
  results.
• Sync wrapper (anymodbus.sync) using the same shared-portal pattern as
  anyserial.sync.
• anymodbus.testing with MockSlave, FaultPlan, and client_slave_pair()
  for hardware-free integration tests.
