Deterministic catalogue remap (no LLM) that re-resolves the stored archetype for
the canonical RdSAP heating descriptions the under-populated taxonomy
mis-classified. Dry-run by default; --apply writes inside a transaction;
idempotent. Updates property_overrides.override_value (TEXT — what the modelling
reads, the actual band-G fix: 3,028 rows incl. 2,210 community boilers + 770
panel/convector room heaters). Cache (the Drizzle-owned main_heating_system
pgEnum) updates are deferred per-value until the FE-repo enum migration adds the
new archetypes — surfaced explicitly by the script.
