Why has this not been implemented

On Friday the 10th this listed-building failed with the error described below, but after a rerun it actually ran cleanly. Given we are going to move these pipelines to pyspark soon, I've decided to drop this work for now, but keeping the PR in case we see this error again before pyspark can be implemented.

Description

Add a memory: 65536 (64 GiB) override to the listed-building / tree-preservation-order
branch in dag_triggers.py (both the scheduled and manual master DAGs).

Why

listed-building-assemble-and-bake failed overnight with a DuckDB out-of-memory error during load_entities_range:

duckdb.duckdb.OutOfMemoryException: failed to pin block of size 4.2 MiB (25.5 GiB/25.5 GiB used)

These two collections already get a CPU bump (16 vCPU) via this branch, but memory stayed at the 32 GiB default, which is the Fargate minimum for 16 vCPU. DuckDB caps itself at 80% of container RAM (25.5 GiB) and hit that ceiling. Root cause is data growth (listed-building now ~387k entities)

Raising to 64 GiB gives DuckDB ~51 GiB usable (2× headroom). 16 vCPU permits up to 120 GiB
if we need to go further.

Which pipelines get affected

• Affects listed-building and tree-preservation-order (they share this branch in airflow which gets compute from fargate).

• Yes
• No, and this is why: we are just configuring airflow not introducing any new features.
