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

+# Decision: Harden NRMSE and Use Metric Profiles in RotatingMachine
+
+- Date: 2026-02-24
+- Scope: `nodes/generalFunctions/src/nrmse/*`, `nodes/rotatingMachine/src/specificClass.js`
+
+## Context
+Drift analytics were previously single-path and flow-focused with weak input safeguards in NRMSE.  
+Requirement: make NRMSE architecturally robust and apply it across multiple measurements in rotatingMachine.
+
+## Decision
+Adopt a metric-profile drift architecture:
+
+1. Harden `generalFunctions/nrmse` with:
+- strict validation for malformed inputs
+- timestamp-aware alignment support
+- per-metric state
+- configurable rolling window and EWMA long-term trend
+- point-based API (`assessPoint`) while retaining legacy calls
+
+2. Rewire rotatingMachine to consume NRMSE per metric:
+- `flow` model drift
+- `power` model drift
+- pressure-quality drift as node-specific plausibility/redundancy assessment
+
+3. Expose drift and confidence outputs per metric in node output payload.
+
+## Consequences
+- Drift computations are deterministic and safer under bad inputs.
+- RotatingMachine confidence now reflects multiple measurement channels.
+- Output schema expands with power/pressure drift fields.
+
+## Rollback Notes
+- Revert `errorMetrics.js` and rotatingMachine drift wiring to return to legacy flow-only drift behavior.
