Worker_Pool.md

Design reasoning

• Workers are isolated: each goroutine reads file paths from the files channel and processes them independently.
• Analyzer logic is injected: the worker pool only depends on the Analyzer interface.
• Extensible: adding a new analyzer is just appending to the analyzers slice in main.go.
• Proper synchronization: a sync.WaitGroup tracks worker lifetimes; results are written to a shared results channel.

Behavior

• Spawn numWorkers goroutines.
• For each incoming file path:
  • Read file contents with os.ReadFile.
  • Find the first analyzer whose Supports method returns true.
  • Call Analyze; if it returns a non-nil result and no error, send it to results.

The worker pool does not know about directory structure or JSON output; it focuses purely on concurrent analysis.
