fix: pass version via CollectConfig instead of hardcoding in orchestrator (#16)

goreleaser sets main.version via ldflags, but the orchestrator had its
own hardcoded "0.4.1" that wouldn't be updated. Now version flows:

  goreleaser → main.version (ldflags) → cfg.Version → orchestrator metadata

Added CollectConfig.Version field. Set in:
- cmd/melisai/main.go (collect command)
- internal/mcp/handlers.go (both get_health and collect_metrics)
- internal/mcp/server.go sets mcpVersion package var on startup
