Fixes a goroutine leak in `pkg/ports.ScanPorts` during premature context cancellation by wrapping the `out <- p` send operation in a `select` block that listens for `ctx.Done()`. When a consumer stops reading from the unbuffered results channel (e.g., due to cancellation), worker goroutines attempting to send discovered ports block indefinitely on `out <- p`, leading to severe goroutine and resource leaks over time in high-concurrency scans. This ensures zero goroutine leakage when context is canceled mid-scan. Co-authored-by: mendsec <12684528+mendsec@users.noreply.github.com>

Fixes a goroutine leak in
pkg/ports.ScanPortsduring premature context cancellation by wrapping theout <- psend operation in aselectblock that listens forctx.Done().Why
When a consumer stops reading from the unbuffered results channel (e.g., due to cancellation), worker goroutines attempting to send discovered ports block indefinitely on
out <- p, leading to severe goroutine and resource leaks over time in high-concurrency scans.Impact
Ensures zero goroutine leakage when context is canceled mid-scan.
Measurement
Verified by running the test suite, specifically tests checking for goroutine leaks upon cancellation.
