znetsixe 495b4cf400 feat: digital (MQTT) mode + fix silent dispatcher bug for camelCase methods ...

Runtime:
- Fix silent no-op when user selected any camelCase smoothing or outlier
  method from the editor. validateEnum in generalFunctions lowercases enum
  values (zScore -> zscore, lowPass -> lowpass, ...) but the dispatcher
  compared against camelCase keys. Effect: 5 of 11 smoothing methods
  (lowPass, highPass, weightedMovingAverage, bandPass, savitzkyGolay) and
  2 of 3 outlier methods (zScore, modifiedZScore) silently fell through.
  Users got the raw last value or no outlier filtering with no error log.
  Review any pre-2026-04-13 flows that relied on these methods.
  Fix: normalize method names to lowercase on both sides of the lookup.

- New Channel class (src/channel.js) — self-contained per-channel pipeline:
  outlier -> offset -> scaling -> smoothing -> min/max -> constrain -> emit.
  Pure domain logic, no Node-RED deps, reusable by future nodes that need
  the same signal-conditioning chain.

Digital mode:
- config.mode.current = 'digital' opts in. config.channels declares one
  entry per expected JSON key; each channel has its own type, position,
  unit, distance, and optional scaling/smoothing/outlierDetection blocks
  that override the top-level analog-mode fields. One MQTT-shaped payload
  ({t:22.5, h:45, p:1013}) dispatches N independent pipelines and emits N
  MeasurementContainer slots from a single input message.
- Backward compatible: absent mode config = analog = pre-digital behaviour.
  Every existing measurement flow keeps working unchanged.

UI:
- HTML editor: new Mode dropdown and Channels JSON textarea. The Node-RED
  help panel is rewritten end-to-end with topic reference, port contracts,
  per-mode configuration, smoothing/outlier method tables, and a note
  about the pre-fix behaviour.
- README.md rewritten (was a one-line stub).

Tests (12 -> 71, all green):
- test/basic/smoothing-methods.basic.test.js (+16): every smoothing method
  including the formerly-broken camelCase ones.
- test/basic/outlier-detection.basic.test.js (+10): every outlier method,
  fall-through, toggle.
- test/basic/scaling-and-interpolation.basic.test.js (+10): offset,
  interpolateLinear, constrain, handleScaling edge cases, min/max
  tracking, updateOutputPercent fallback, updateOutputAbs emit dedup.
- test/basic/calibration-and-stability.basic.test.js (+11): calibrate
  (stable and unstable), isStable, evaluateRepeatability refusals,
  toggleSimulation, tick simulation on/off.
- test/integration/digital-mode.integration.test.js (+12): channel build
  (including malformed entries), payload dispatch, multi-channel emit,
  unknown keys, per-channel scaling/smoothing/outlier, empty channels,
  non-numeric value rejection, getDigitalOutput shape, analog-default
  back-compat.

E2E verified on Dockerized Node-RED: analog regression unchanged; digital
mode deploys with three channels, dispatches MQTT-style payload, emits
per-channel events, accumulates per-channel smoothing, ignores unknown
keys.

Depends on generalFunctions commit e50be2e (permissive unit check +
mode/channels schema).
