  * Add dynamic gas fee configuration per SWQOS service and trade type
  * Integrate arc-swap for thread-safe strategy updates

- docs: restructure documentation with dedicated guides
  * Add ADDRESS_LOOKUP_TABLE.md/CN.md for lookup table configuration
  * Add NONCE_CACHE.md/CN.md for nonce management documentation
  * Add TRADING_PARAMETERS.md/CN.md for comprehensive parameter guides
  * Simplify main README.md with focused overview

- refactor: update all examples with new gas fee strategy integration
