📝 Summary

Summary by CodeRabbit

• Documentation
  • Added a cloud-native service roadmap covering scalability, resilience, security, observability, deployment, and phased milestones.
• Bug Fixes
  • Reputation override operations now include individual failures in the returned error, making issues easier to detect.
  • Improved cleanup handling across database, HTTP response, and event-iterator operations.
  • Preserved existing user-operation hash validation and gas-estimation response behavior.

The pull request adds a roadmap for evolving the bundler into a cloud-native service. It also makes small Go changes to deferred cleanup, validation expressions, reputation error accumulation, and tests.

Changes: Cloud-native roadmap

Layer / File(s)	Summary
Scope and storage design CLOUD_NATIVE_ROADMAP.md	The roadmap describes current constraints and specifies storage interfaces, local and shared backends, and distributed coordination requirements.
Signer and node capabilities CLOUD_NATIVE_ROADMAP.md	The roadmap specifies signer interfaces and verification, along with per-chain node configuration and capability detection.
Configuration and operations CLOUD_NATIVE_ROADMAP.md	The roadmap defines replica behavior, shutdown and health requirements, configuration, observability, and security requirements.
Validation and delivery CLOUD_NATIVE_ROADMAP.md	The roadmap lists test and deployment deliverables, implementation phases, and completion criteria.

Go maintenance updates

Layer / File(s)	Summary
Deferred resource cleanup cmd/healthcheck.go, internal/start/*, pkg/altmempools/directory.go, pkg/entrypoint/filter/*, pkg/entrypoint/v07/filter/*, pkg/entrypoint/v08/filter/*, pkg/entrypoint/v09/filter/*, pkg/mempool/instance_test.go, pkg/modules/context_test.go, tests/main_test.go	Deferred response, database, and iterator cleanup now explicitly discards close errors. Database test cleanup uses closures that discard close errors.
Validation and error handling pkg/modules/entities/reputation.go, pkg/entrypoint/simulation/entityrules.go, pkg/entrypoint/v07/filter/hash.go, pkg/entrypoint/v08/filter/hash.go, pkg/entrypoint/v09/filter/hash.go	Reputation override errors are accumulated. The entity rule and hexadecimal character checks are rewritten with the same outcomes described in the change summaries.
Other code and test adjustments internal/testutils/rpcmock.go, pkg/client/client.go, pkg/client/utils.go, pkg/bundler/bundler_test.go	The RPC mock writes its formatted response directly. The client retains a legacy field with a staticcheck suppression. The reflection check and test sanity check are adjusted.

_{I’m a rabbit with a roadmap to read,
And neat little closes tucked in with care.
Hex checks hop along their familiar way,
Joined errors now gather instead of stray.
I nibble the diff, then bound away.}
