v0.3.2

[0.3.2] - 2026-10-01

Added

• async: Concurrency orchestration package with panic-safe Go, context-aware GoCtx, fan-out Parallel with first-error cancellation, and bounded ParallelLimit using semaphores for worker quota protection.
• fsm: Declarative in-memory Finite State Machine with $O(1)$ compiled transition table lookups, CanTransition, and structured ValidateTransition errors.
• uuidutil: Centralized RFC 4122 UUID manipulation helpers (New, NewString, ParsePtr, MustParse, IsValid, IsNil).
• pagination: Added PaginateSlice[T any] and PageMeta in slice.go for bounds-safe generic slice slicing preventing out-of-bounds slice indexing.
• jwks: Thread-safe in-memory cached ECDSA P-256 JWKS public key resolver with 2-hour TTL and network-interruption stale fallback.
• ginmw:
  • RequireTenant middleware with flexible source extraction (Gin context, claims, x-tenant-id header, or query parameters) and role-based bypass (WithBypassRoles).
  • Standardized JSON response helpers (RespondSuccess, RespondCreated, RespondError, RespondErrorWithDetail) implementing JSend-compatible Envelope[T any].
  • Lock-free, low-latency RED metrics middleware (REDMetrics) and Prometheus text/JSON /metrics endpoint handler (MetricsEndpoint).
