wiki: rewrite Home.md per visual-first 14-section template

- Run npm run wiki:all (wiki:contract + wiki:datamodel both wrote cleanly)
- Remove section 10 (State chart) — measurement is stateless, no FSM
- Renumber sections 11→10, 12→11, 13→12, 14→13 for correct 13-section layout
- Update banner git hash from afc304b to 125f964

-**Skipped** — measurement is a pure pipeline. There is no FSM. The only mode switch (analog vs digital) is decided once at `configure()` time and never transitions thereafter; see section 4 for the static branching diagram.

 - Don't use measurement to **fuse** signals from multiple sensors — it's per-channel only. Aggregate at the parent.
 - Don't use measurement for **control output** — it's read-only signal conditioning. Use `rotatingMachine` / `valve` for actuation.
 - Don't use measurement for **alarm logic** — there is no threshold-trip output. Build that on top of the emitted reading at the parent or in a dashboard rule.
