fix: address review findings — dedupe extraction, fix Temporal modeling

1. Move extractQueuePatterns() to shared utility module
   (utils/queue-extraction.ts) eliminating copy-paste between
   parse-worker.ts and pipeline.ts.

2. Fix Temporal semantic modeling:
   - Extract actual taskQueue name from workflow.start() options
     instead of using the workflow function name
   - Activity calls now create ENQUEUES edges (producer), not
     PROCESSES edges — they dispatch work, not consume it
   - Add proxyActivities guard to avoid false positives on generic
     activities.foo() calls in non-Temporal code
   - Simplify role union to 'producer' | 'consumer'

3. Add integration tests verifying taskQueue extraction and
   proxyActivities guard behavior.
