refactor: Phase 4 - split worker package into focused files
Split 551-line worker/core.go into single-concern files:

- worker/config.go (+44 lines)
  - Added config parsing: envInt(), parseCPUFromConfig(), parseGPUCountFromConfig()
  - parseGPUSlotsPerGPUFromConfig()
  - Now has all config logic in one place (440 lines total)

- worker/metrics.go (new file, 172 lines)
  - Extracted setupMetricsExporter() with ~30 Prometheus metric registrations
  - Isolated metrics logic for easy modification

- worker/factory.go (new file, 183 lines)
  - Extracted NewWorker() factory function
  - Moved prePullImages(), pullImage() from core.go
  - Centralized worker instantiation

- worker/worker.go (renamed from core.go, ~100 lines)
  - Now just defines Worker struct, MLServer, JupyterManager
  - Clean, focused file without mixed concerns

Lines redistributed: ~350 lines moved from monolithic core.go
Build status: Compiles successfully
