* refactor(cli): extract per-target scan into scanTarget
pull the target loop body into scanTarget, which returns a targetScan
holding that target's findings, report rows, scan labels and log files
instead of appending onto run-wide slices. the run loop merges those in
target order and finishRun handles the post-loop notify/silent/report/
summary steps. behavior is identical for the sequential run today; the
isolation is the seam a bounded worker pool needs next.
* feat(cli): scan targets in parallel with -concurrency
add -concurrency N (default 1) to run the per-target scan pool over
several targets at once. scanTarget already returns isolated
accumulators, so workers share only the console: output.SetConcurrent
serializes sink writes and de-animates spinners/progress so parallel
lines stay whole. results merge in input order, and concurrency 1 keeps
the sequential path unchanged.
sif can now slot into unix pipelines. stdin is drained for targets when
it's a pipe (keyed off stdin's mode, not stdout), alongside -u/-f. naked
hosts are accepted and default to https://; explicit http(s) is kept,
other schemes rejected. -silent routes all banner/spinner/log chrome to
stderr and prints one normalized finding per line to stdout via
finding.Flatten, so `subfinder | sif -silent | notify` works.
rolls the (c) 2022-2025 banner to 2022-2026 across all go files, the
startup banner in sif.go, and the header-check workflow's expected
format. comment-only, nothing else changes.
- Add output package with colored prefixes and module loggers
- Each module gets unique background color based on name hash
- Add spinner for indeterminate operations
- Add progress bar for known-count operations
- Update all scan files to use ModuleLogger pattern
- Add clean PrintSummary for scan completion
