Migrate to new Gitea instance (gitea.wbd-rd.nl)

- Update all submodule URLs from gitea.centraal.wbd-rd.nl to gitea.wbd-rd.nl
- Add settler as proper submodule in .gitmodules
- Add agent skills, function anchors, decisions, and improvements
- Add Docker configuration and scripts
- Add manuals and third_party docs
- Update .gitignore with secrets and build artifacts
- Remove stale .tgz build artifact

+description: Engineer OT edge connectivity and PLC interoperability for EVOLV. Use when implementing or reviewing OPC UA/Modbus and similar integrations, namespace/tag mapping, quality/timestamp semantics, retry/reconnect behavior, and deterministic command/feedback contracts at the edge.

+
+# EVOLV OT Edge PLC Integration
+
+## Mission
+Deliver reliable, deterministic edge protocol integration between EVOLV Node-RED nodes and PLC/SCADA systems.
+
+## Harness Execution Contract
+- Start from current integration topology, topic contracts, and protocol endpoints.
+- Define invariants before edits:
+  - command/feedback contracts remain deterministic
+  - reconnect/retry behavior is bounded and observable
+  - quality/timestamp semantics are preserved end-to-end
+- Validate with connection-loss and recovery evidence.
+
+## Scope
+- Edge/connector nodes (existing and new)
+- Topic mapping code in `nodes/*/src/`
+- Admin endpoints/config for connector behavior and credentials
+
+## Workflow
+1. Map PLC tags/NodeIds/registers to EVOLV message contracts.
+2. Define write acknowledgement and feedback confirmation rules.
+3. Implement reconnect/backoff/session handling.
+4. Enforce quality, timestamp, and stale-value semantics.
+5. Verify failover behavior and command idempotency.
+
+## Standards
+- Never assume connection continuity; model transient faults explicitly.
+- Keep protocol mappings versioned and auditable.
+- Separate transport errors from process-state errors.
+- Ensure secure defaults align with OT/IT security skill.
+
+## Test Expectations
+Cover:
+- disconnect/reconnect and session re-establish paths
+- duplicate/late/out-of-order message handling
+- read/write mapping correctness and unit conversion
+- safe behavior under degraded quality or timeout
+
+## Deliverables
+Return:
+- integration contract map (protocol <-> topic/payload)
+- retry/recovery strategy and limits
+- changed files/tests with failure-injection evidence
+- operational rollout risks and mitigations
+
+Decision interview triggers:
+- command authority or handshake behavior changes
+- protocol mapping breaks requiring migration
+- timeout/retry strategy changes affecting availability/safety
