Improve and fix all issues and errors in the repository
Refactor and enhance error handling, improve documentation, and expand test cases. * **cmd/geth/main.go** - Remove redundant license comments. * **core/bloom_indexer.go** - Add error handling for bloom generator initialization. - Add error handling for bloom addition and bitset retrieval. - Fix typo in comment. * **core/chain_indexer_test.go** - Add tests for chain indexer reorg handling. - Add tests for chain indexer pruning. * **core/bloombits/generator_test.go** - Add tests for edge cases in bloom generator. * **core/bloombits/matcher_test.go** - Add tests for edge cases in matcher. * **core/bloombits/scheduler_test.go** - Add tests for edge cases in scheduler. --- For more details, open the [Copilot Workspace session](https://copilot-workspace.githubnext.com/ethereum/go-ethereum?shareId=XXXX-XXXX-XXXX-XXXX).
