Add eval harness + Tier 2/3 mode template pages

Browse Source 
### eval/ (scenario-based evaluation)

Complements the unit tests under test/basic. Scenarios fluctuate inputs
over simulated time, record every tick to JSONL, print a summary
table + event log, and check expectations. Complementary to unit
tests — these answer "how does the system respond to this input
profile" rather than "is this function correct".

- eval/run.js             — driver; monkey-patches Date.now so the
                            volume integrator ticks at 1 s/iter
                            regardless of wall-clock
- eval/scenarios/         — one file per scenario
  - levelbased-steady.js  — constant inflow, demand converges
  - levelbased-storm.js   — inflow surge, demand saturates
  - safety-dry-run-trip.js — manual mode, empty basin, safety trips
- eval/formatters/table.js — ASCII summary of sampled ticks
- eval/logs/              — per-scenario JSONL output (one line per tick)
- eval/README.md          — usage + scenario file shape + how to pipe
                            into InfluxDB/Grafana

All three starter scenarios PASS with their expectations.

### wiki/modes/ (tier template pages)

The levelbased page templated Tier-1 modes (static transfer function).
Added worked examples for the other two tiers so all mode pages share
a common skeleton and new modes have something concrete to imitate:

- flowbased.md   — Tier 2 (PID on measured outflow)
- powerbased.md  — Tier 2 (levelbased curve clipped by grid power budget)
- mpc.md         — Tier 3 (optimisation + forecast; block diagram +
                           scenario time-series instead of a fixed curve)

- modes/README.md — updated with the three-tier classification table
                    and diagram-type-per-tier guidance

# Control modes
Each page describes one `pumpingStation` control mode and how it uses the shared [basin model](../functional-description.md#basin-model) — specifically, how it sets the three control thresholds (`minLevel`, `startLevel`, `maxLevel`) and computes the demand it sends to the MGC.

The two **safety** thresholds (`dryRunLevel` and `overflowLevel`) are mode-independent and are enforced by the safety layer outside any mode. They never appear in a mode's policy.

Every mode page follows the same structure:
1. **At a glance** — one sentence + small fact table (inputs, output, status)
2. **Diagram** — reference to `../diagrams/modes/<mode>.drawio.svg`
2. **Diagram** — one or more, per tier (see below)
3. **Inputs** — what signals the mode reads
4. **Threshold policy** — how it sets/adjusts `minLevel`, `startLevel`, `maxLevel`
5. **Demand formula** — how it turns inputs into a 0-100 % demand for the MGC
4. **Threshold policy** — how it uses / adjusts `minLevel`, `startLevel`, `maxLevel`
5. **Demand formula** — pseudocode for Tier 1/2, objective function for Tier 3
6. **Edge cases** — cold start, sensor dropout, interaction with safety layer
7. **Related** — links to other modes + functional description
The three **tiers** classify modes by how dynamic the decision surface is:
| Tier | Curve | Example modes | Diagram type |
|---|---|---|---|
| **1** — static | Memoryless `demand = f(x)`; single curve | `levelbased`, `manual` | Single-curve transfer function |
| **2** — parameterised | Shape fixed, curve moves with θ(t) | `flowbased`, `pressureBased`, `percentageBased`, `powerBased` | Transfer function + parameter overlay / family |
| **3** — horizon-based | Optimisation, no fixed curve | `hybrid-optimal`, `mpc`, weather-aware | Block diagram of signal flow + scenario time-series |
