Prep for the Werkbank Docker executor (sharang/werkbank#5): the dynamic-execution
logic has to be usable by the runner (a separate repo), so lift it out of the
agent into a shared crate.
New crate `werkbank-exec` (git-mv preserves history):
- src/ics/* — the read-only industrial-protocol probe (Modbus/OPC-UA/
EtherNet-IP/portscan), moved verbatim.
- src/plc/* — ephemeral soft-PLC provisioning (DockerSoftPlc), the OpenPLC
program-load client, and provision_and_test/extract_program.
- src/error.rs — a crate-local ExecError, replacing the agent's AgentError.
- src/fingerprint.rs — compute_fingerprint (copied from the agent's dedup).
Depends only on compliance-core + compliance-dast, so the runner can pull it
without the agent's server stack.
compliance-agent consumes it:
- AgentError gains `Exec(#[from] werkbank_exec::ExecError)`.
- The orchestrator's ICS-probe + provision-and-test call sites point at
werkbank_exec::{ics,plc}; the old pipeline::ics and plc::runtime modules are
removed (the static PLC scanner stays).
- CI clippy-checks + tests the new crate.
Pure move + rename — no behaviour change. 27 moved tests pass in the new crate;
283 agent lib tests pass; clippy + fmt clean.
