feat: initial stats-cohort-size v0.1.0 (stats.cohort_size@0.1.0)
Resolve the size of an addressee cohort (e.g. "Berliner KMU",
"Gastronomie deutschlandweit").
v0.1.0 ships a five-entry built-in lookup for the F∆I Law-Heatmap
pilot corpus:
berlin-kmu, de-kmu, gastro-de, handwerk-be, bauwirtschaft-be
Each entry carries (count, year, source, tier). Tier follows the
Studie §6.7 Regel-der-niedrigsten-Stufe: T1 when from DESTATIS
Unternehmensregister, T2 when from a Verband source.
Reuse-lens: any quantitative analysis that needs cohort sizing —
market research, audience targeting, public-health tracking.
Pure in-WASM, zero filesystem, zero network.
Reserved for next versions:
- 0.2: DESTATIS GENESIS-API adapter — requires
net: ["genesis.destatis.de"] permission. Interface stays
the same; the static lookup becomes the fallback when
the API is unreachable.
- 0.3: WZ-Code-resolved sub-cohorts (e.g. "berlin-kmu-wz56").
