- --log-level (comma-separated string: info, error): pick which logs are emitted;
the level set is resolved once, up front
- Log responses at the info level: full self-contained JSON to a file or stderr,
a compact "status duration | body" summary in the TUI log box
- Route logs independently of the progress display: the TUI log box when it runs,
stderr when piped, or a file via --log-file/-w (parent dir validated up front)
- Replace --quiet with --progress (bar | none, default bar): progress and logs are
now independent — progress=none still shows the log box; quiet == progress=none
with an empty log level
- Rename the internal "message" concept to "log" (runtimeLog, runtimeLogger, ...)
- Rename Append to Merge on Cookies, Headers, and Params types and simplify Parse to use direct append
- Replace strings_Join(sep, ...values) with slice_Join(slice, sep) for consistency with slice-based template functions
- Auto-enable quiet mode when stdout is not a terminal
- Remove ErrCLINoArgs check to allow running sarin without arguments
- Add -it flag to Docker examples in docs
