- Driver.Modbus.Addressing-006: broaden the catch in TryParseFamilyNative
so a future helper throwing a non-Argument/Overflow type still satisfies
the try-parse contract.
- Driver.Modbus.Addressing-007: document that the address grammar does
not carry ModbusStringByteOrder (the structured-tag path does);
add a 'Grammar scope' bullet to docs/v2/dl205.md.
- Driver.Modbus.Addressing-009: reword the ModbusModiconAddress comments
so they don't imply a leading-digit invariant the parser doesn't
enforce.

The DL205 family-native branch routed every V-prefixed address through
DirectLogicAddress.UserVMemoryToPdu, a plain octal-to-decimal decode.
DL205/DL260 system V-memory (V40400 and up) is not a simple octal decode:
the CPU relocates the system bank to Modbus PDU 0x2100. Octal-decoding
V40400 produced 16640 (0x4100), the wrong register, so any tag addressing
a system register through the grammar string silently read/wrote the
wrong PLC memory.
- Add DirectLogicAddress.VMemoryToPdu, which decodes the octal V-address,
detects the system bank (octal >= V40400 == SystemVMemoryOctalBase) and
relocates it through SystemVMemoryToPdu to PDU 0x2100; user-bank
addresses keep the plain octal decode.
- ModbusAddressParser's DL205 V branch now calls VMemoryToPdu instead of
UserVMemoryToPdu. UserVMemoryToPdu is retained for user-bank-only callers.
- Correct the ModbusFamilyParserTests V40400 assertion (16640 -> 0x2100)
and add system-bank regression cases plus direct helper coverage.

Group all 69 projects into category subfolders under src/ and tests/ so the
Rider Solution Explorer mirrors the module structure. Folders: Core, Server,
Drivers (with a nested Driver CLIs subfolder), Client, Tooling.
- Move every project folder on disk with git mv (history preserved as renames).
- Recompute relative paths in 57 .csproj files: cross-category ProjectReferences,
the lib/ HintPath+None refs in Driver.Historian.Wonderware, and the external
mxaccessgw refs in Driver.Galaxy and its test project.
- Rebuild ZB.MOM.WW.OtOpcUa.slnx with nested solution folders.
- Re-prefix project paths in functional scripts (e2e, compliance, smoke SQL,
integration, install).
Build green (0 errors); unit tests pass. Docs left for a separate pass.
