Zixir v5.1.0 — Hotfix: Shared utils, dedup, config, engine retry fix

Hotfix release: shared utilities module, elimination of code duplication, centralized configuration, and a critical engine retry bug fix.

1. Created Shared Utilities Module ✅

• New file: lib/zixir/utils.ex
• Functions: format_bytes/1, generate_id/1, now_ms/0, iso8601_now/0
• Centralized helpers used across the codebase

2. Eliminated Code Duplication ✅

• Removed 8 duplicate function clauses from 2 files
• Updated 5 modules to use centralized ID generation
• Files affected: cache.ex, sandbox.ex, workflow.ex, quality.ex, experiment.ex, checkpoint.ex

3. Centralized Configuration ✅

• New config values in config/config.exs:
  • python_timeout: 30_000
  • workflow_step_timeout: 30_000
• Files updated: worker.ex, pool.ex, workflow.ex
• All now read from config instead of hardcoded values

4. Fixed Critical Bug ✅

• File: lib/zixir/engine.ex
• Problem: Infinite loop risk in rescue block
• Solution: Added retry tracking to prevent endless retries
