feat: T4b/T4c wave 8 - weather history, phenology, honey chain, Telegram base

- Weather history from Open-Meteo behind an adapter: worker loop
  phenology-weather with backoff, Retry-After, User-Agent, chunked
  writes and forecast-to-archive correction
- Phenology: growing degree sum per DWD, phase from reports, GTS and
  calendar, calibration from previous years, daily job step,
  SeasonService reads the stored state
- Honey chain: prefill for extractions and batches (proposals only),
  plausibility and withdrawal warnings, Extraction lock, chain events
  and batch.created webhook from HoneyBatchRecorded
- Telegram base: schema, NotificationDelivery outbox, hardened bot
  client, startup check without crash, no-network-outside-loops guard
- ARCHITECTURE.md: sections 11.11-11.13, assumptions 42-46, env table
