55279ca78f docs(plc): as-built copy, versions, and a getting-started guide
Adds what the folder was missing for someone picking it up cold.

as-built/  the STruC++ output copied out of the live container - the C++
           the PLC is actually executing, plus program.st and the Modbus
           buffer config. The running image was made with docker commit
           and exists in no registry, so this is the only other copy of
           the compiled form.

           Verified while copying: the deployed program.st matches
           build/wrps.st generated from src/. Identical POU structure,
           ZERO differences in non-declaration lines. src/ is genuinely
           canonical and the running PLC agrees with it.

VERSIONS.md         every version read from the running system, not from
                    documentation: runtime v4.1.10, STruC++ 0.6.2, Editor
                    4.2.11, Debian 12, g++ 12.2, pymodbus 3.11.2, CI
                    Server R1.03. Plus which plugins are enabled -
                    ethercat is on for no reason - and a v3-vs-v4 table,
                    since most OpenPLC guidance online is for v3 and the
                    %MW HR1024 change silently produces wrong data.

GETTING-STARTED.md  three questions answered in a page: how to modify the
                    program, how to stand up a new PLC container from
                    scratch, how to move this one. Includes the compose
                    file, the Editor steps that are not generated and are
                    always missed, and a symptom-to-document table.

13a05d0135 feat(plc): ST sources, generators and the Modbus contract
The PLC program from the old repo's 04-plc/, flattened into one folder and
checked against the running system.

Verified during the move:
  - build.py regenerates register-map.csv byte-identically (69 points)
  - polled the live PLC: the SIMULATION build is what is deployed and
    running, %MW21=2 wet weather, values moving, run hours accumulating
  - addresses, %MW HR1024 segmentation and %QW17/%QW7 signedness all
    match the map

Corrections against the old repo:
  - 10_globals.st header cited WRPS-CTL-002 (the FDS); it means CTL-003
  - build.py wrote the map to its parent directory; now beside itself
  - deploy/README.md was a single-file folder; now DEPLOY.md
  - dropped the empty editor-devices/remote/
  - README no longer claims the simulation build is uncompiled - it is
    the one running

Two open items are now stated plainly rather than buried:
  - none of the 20 acceptance tests in CTL-003 have ever been run
  - the OpenPLC Editor lived only on the retired dev-ubuntu host, so
    there is currently NO route to deploy a new program (DEPLOY.md 0)

Documents the setpoint distinction: IO_MUX seeds %MW defaults once at
first scan, operators retune them live, and that tuning exists only in
the container volume - a restart reverts it.
