Improve remaining locality GeoNames ID coverage after v0.1.3

[mustafazeydani]

v0.1.3 intentionally leaves locality-level GeoNames ID coverage partial.

Current release coverage:

• Localities: 7,605
• Localities with GeoNames IDs: 4,274
• Localities still missing GeoNames IDs: 3,331
• GeoNames locality ID coverage: 56.2%

Progress since this issue was opened:

• v0.1.2 added 281 widened-radius one-to-one GeoNames locality matches using exact normalized names and same-governorate checks.
• v0.1.3 added 225 Arabic article-insensitive one-to-one GeoNames locality matches within 2 km.
• The reusable matcher now supports dry-run/apply modes and selected Arabic article-insensitive variants.

Current concentration of missing GeoNames IDs by governorate:

• Aleppo: 919
• Al-Hasakah: 876
• Raqqa: 393
• Idlib: 291
• Hama: 223
• Homs: 158
• Latakia: 129
• Tartus: 109
• Deir-ez-Zor: 96
• Daraa: 44
• Rif Dimashq: 42
• Quneitra: 30
• As-Suwayda: 21
• Damascus: 0

Notes:

• Do not infer IDs from name similarity alone.
• Keep every accepted ID source-backed and documented through an import manifest.
• Review remaining candidates in focused governorate batches, starting with Aleppo and Al-Hasakah.
• If a locality has no safe GeoNames match, leave it unresolved until a stronger approved source exists.
