The v2 module path is github.com/sony/gobreaker/v2 and the breaker is
generic. The code instantiates it with any, which matches the v1
Execute signature.
The circuit breaker ignored the trip-on-timeout, trip-on-4xx, and
trip-on-5xx flags and never cleared its counts, so the failure ratio
became lifetime-cumulative. The backoff-multiplier and max-backoff
settings did nothing. Circuit-open surfaced as HTTP 500.
Failure classification now honours the trip flags, the breaker uses a
rolling count window, and repeated trips extend the open state up to the
configured maximum. A helper maps circuit-open to HTTP 503. The request
body is copied once per request instead of once per retry. Defaults
reproduce the prior behaviour: the breaker is off by default and a
backoff multiplier of one keeps a constant open window.
* chore(security,refactor): extract sanitization and improve code quality

- [x] Add admin API authentication security warning
- [x] Extract WebSocket and stats streaming constants
- [x] Add best-effort error handling comments for resource cleanup
- [x] Expand sensitive field patterns for improved PII redaction
- [x] Simplify safety checks and remove redundant nil validations
- [x] Improve test coverage for password field redaction patterns
* refactor: replace interface{} with any type alias
- [x] Replace all `map[string]interface{}` with `map[string]any`
- [x] Replace all `interface{}` with `any` in function signatures and type definitions
- [x] Update sync.Pool New function returns from `interface{}` to `any`
- [x] Add package documentation comments to 8 package files
- [x] Update type assertions and casts to work with `any` type
