Evan Rusackas cb005a2ea5 feat(country-map): build script — territory_assignments transform ...

Implements the third transform: pull features from sibling Admin 0
records into a destination country's Admin 1 view. Used for:
- China + Taiwan/HK/Macau (NE keeps each as separate Admin 0)
- Finland + Åland (missing from FIN admin 1; NE keeps Åland as ALD
  admin 0)

Verified on real data:
  Building worldview=ukr admin_level=1
    territory_assignments: added 4 features from sibling Admin 0 records

(4 = TWN/HKG/MAC + ALD; ARMM-renamed BARMM region picks up correctly
because name_overrides ran first.)

Two bugs fixed along the way:

1. **Property name casing.** NE Admin 0 ships with uppercase property
   names (ADM0_A3, NAME_EN), Admin 1 with lowercase. All transforms
   downstream assume lowercase, so we now normalize to lowercase at
   shapefile-conversion time. Bonus: fixes a silent flying_islands
   bug where `adm0_a3` filters never matched at Admin 0 because the
   props were uppercase.

2. **drop_outside_bbox at Admin 0.** A country's multi-polygon often
   includes overseas territories (Netherlands → Caribbean), so bbox
   filtering at Admin 0 would drop entire countries. Now guarded to
   only run at Admin 1 where each feature is a single subdivision.

3. **Åland's NE code.** NE uses ALD, not the ISO 3166-1 ALA. Updated
   territory_assignments.yaml with comment noting the divergence.
