Summary

Implemented Middleware base class (lib/aethyr/core/commands/middleware.rb) with priority ordering (default 500), phase designation (:before_action/:after_action), call(action, context) interface, and class-level register method
Implemented MiddlewarePipeline executor (lib/aethyr/core/commands/middleware_pipeline.rb) with Mutex-protected registry, priority-sorted before/after phases, and throw(:halt) chain interruption mechanism
Added 19 Cucumber BDD scenarios covering execution order, halt behavior, argument validation, context passing, class-level registration, and edge cases

Closes #105

Implementation Details

Thread-safe: Registry is protected by a Mutex; snapshot_middleware extracts before/after lists under the lock, then execution proceeds without holding the lock
Immutable defaults: VALID_PHASES is frozen; priority and phase are set at construction time
Argument validation: All public methods validate types per CONTRIBUTING.md (nil checks, type verification, value range for phases)
Sorbet typed: Both source files use # typed: strict with full sig annotations
RuboCop clean: 0 offenses on all new files
Full BDD coverage: 19 scenarios, 74 steps, all passing

## Summary - Implemented `Middleware` base class (`lib/aethyr/core/commands/middleware.rb`) with priority ordering (default 500), phase designation (:before_action/:after_action), `call(action, context)` interface, and class-level `register` method - Implemented `MiddlewarePipeline` executor (`lib/aethyr/core/commands/middleware_pipeline.rb`) with Mutex-protected registry, priority-sorted before/after phases, and `throw(:halt)` chain interruption mechanism - Added 19 Cucumber BDD scenarios covering execution order, halt behavior, argument validation, context passing, class-level registration, and edge cases Closes #105 ## Implementation Details - **Thread-safe**: Registry is protected by a Mutex; `snapshot_middleware` extracts before/after lists under the lock, then execution proceeds without holding the lock - **Immutable defaults**: `VALID_PHASES` is frozen; priority and phase are set at construction time - **Argument validation**: All public methods validate types per CONTRIBUTING.md (nil checks, type verification, value range for phases) - **Sorbet typed**: Both source files use `# typed: strict` with full `sig` annotations - **RuboCop clean**: 0 offenses on all new files - **Full BDD coverage**: 19 scenarios, 74 steps, all passing

Implemented the Middleware base class with priority ordering, phase
designation (before_action/after_action), and class-level registration.
Added the MiddlewarePipeline executor with priority-sorted before/after
phases and throw(:halt) chain interruption mechanism. Thread-safe
Mutex-protected registry. Full Cucumber BDD coverage including priority
ordering, halt behavior, argument validation, and context passing.
