Real LVGMC FTP credentials arrived today; real DMI HARMONIE
credentials haven't. The combined flag would have enabled both the
moment FTP's were ready, crash-looping the app on HARMONIE's still-
placeholder values via parMapN — caught this before it happened
(the Grib job was ~15 min from its first scheduled run). Split into
ENABLE_LVGMC_FTP_JOBS and ENABLE_HARMONIE_JOBS so each provider can
be enabled independently as its own credentials become real.
ARCHITECTURE.md, PRODUCT_WORKFLOWS.md, DEVELOPMENT_AND_STAGING.md, and
README.md still described the removed synthetic-seed staging setup and
Ūdens as pure manual entry. Updates this session (open-data station
ingestion, the scheduler split, water-temperature auto-populate)
weren't reflected outside UPDATE_ROADMAP.md's changelog.
