zeekayandEthereum Foundation <https://github.com/ethereum/go-ethereum> 347b448823 Merge latest go-ethereum upstream (v1.16.6) into luxfi/geth
Merged upstream changes from go-ethereum master branch (commit fb3c8f462)
while preserving luxfi branding and package structure.

Key changes:
- Updated to go-ethereum v1.16.6 (patch version bump from v1.16.5)
- Preserved luxfi module name (github.com/luxfi/geth)
- Preserved luxfi branding in LICENSE (Lux Industries Inc.)
- Maintained LuxMainnetChainConfig and LuxTestnetChainConfig
- All import paths use github.com/luxfi/geth (not ethereum)
- Added Lux genesis hashes for network identification
- Integrated new upstream features:
  * Enhanced blob pool with conversion support
  * New keccak256 preimage tracer
  * Transaction pool validation improvements
  * State sizing utilities
  * Filter system enhancements
  * Various performance and stability improvements

Build verified: geth v1.16.6-unstable compiled successfully
