refactor: Phase 3 - fix config/storage boundaries 
Move schema ownership to infrastructure layer:

- Redis keys: config/constants.go -> queue/keys.go (TaskQueueKey, TaskPrefix, etc.)

- Filesystem paths: config/paths.go -> storage/paths.go (JobPaths)

- Create config/shared.go with RedisConfig, SSHConfig

- Update all imports: worker/, api/helpers, api/ws_jobs, api/ws_validate

- Clean up: remove duplicates from queue/task.go, queue/queue.go, config/paths.go

Build status: Compiles successfully

refactor: extract domain types and consolidate error system (Phases 1-2) 
Phase 1: Extract Domain Types
=============================
- Create internal/domain/ package with canonical types:
  - domain/task.go: Task, Attempt structs
  - domain/tracking.go: TrackingConfig and MLflow/TensorBoard/Wandb configs
  - domain/dataset.go: DatasetSpec
  - domain/status.go: JobStatus constants
  - domain/errors.go: FailureClass system with classification functions
  - domain/doc.go: package documentation

- Update queue/task.go to re-export domain types (backward compatibility)
- Update TUI model/state.go to use domain types via type aliases
- Simplify TUI services: remove ~60 lines of conversion functions

Phase 2: Delete ErrorCategory System
====================================
- Remove deprecated ErrorCategory type and constants
- Remove TaskError struct and related functions
- Remove mapping functions: ClassifyError, IsRetryable, GetUserMessage, RetryDelay
- Update all queue implementations to use domain.FailureClass directly:
  - queue/metrics.go: RecordTaskFailure/Retry now take FailureClass
  - queue/queue.go: RetryTask uses domain.ClassifyFailure
  - queue/filesystem_queue.go: RetryTask and MoveToDeadLetterQueue updated
  - queue/sqlite_queue.go: RetryTask and MoveToDeadLetterQueue updated

Lines eliminated: ~190 lines of conversion and mapping code
Result: Single source of truth for domain types and error classification

perf: add profiling benchmarks and parallel Go baseline for C++ optimization 
Add comprehensive benchmarking suite for C++ optimization targets:
- tests/benchmarks/dataset_hash_bench_test.go - dirOverallSHA256Hex profiling
- tests/benchmarks/queue_bench_test.go - filesystem queue profiling
- tests/benchmarks/artifact_and_snapshot_bench_test.go - scanArtifacts/extractTarGz profiling
- tests/unit/worker/artifacts_test.go - moved from internal/ for clean separation

Add parallel Go implementation as baseline for C++ comparison:
- internal/worker/data_integrity.go: dirOverallSHA256HexParallel() with worker pool
- Benchmarks show 2.1x speedup (3.97ms -> 1.90ms) vs sequential

Exported wrappers for testing:
- ScanArtifacts() - artifact scanning
- ExtractTarGz() - tar.gz extraction
- DirOverallSHA256HexParallel() - parallel hashing

Profiling results (Apple M2 Ultra):
- dirOverallSHA256Hex: 78% syscall overhead (target for mmap C++)
- rebuildIndex: 96% syscall overhead (target for binary index C++)
- scanArtifacts: 87% syscall overhead (target for fast traversal C++)
- extractTarGz: 95% syscall overhead (target for parallel gzip C++)

ea15af1833 Fix multi-user authentication and clean up debug code 
- Fix YAML tags in auth config struct (json -> yaml)
- Update CLI configs to use pre-hashed API keys
- Remove double hashing in WebSocket client
- Fix port mapping (9102 -> 9103) in CLI commands
- Update permission keys to use jobs:read, jobs:create, etc.
- Clean up all debug logging from CLI and server
- All user roles now authenticate correctly:
  * Admin: Can queue jobs and see all jobs
  * Researcher: Can queue jobs and see own jobs
  * Analyst: Can see status (read-only access)

Multi-user authentication is now fully functional.
