v2.5.9: utls dual-probe + JA4/JA4S + TCP behavior fingerprint

v2.5.8: monolith -> modular tree refactor + shared SSL_CTX perf

v2.5.7: --save scan output to file (#7)

new --save flag dumps a copy of the scan into <target>.md (or an
explicit path if given). tee-style: every printf/puts call goes both
to stdout (with ansi colors as before) AND to the save file (with
ansi escapes stripped). file is wrapped in a markdown code block.

terminal output is byte-identical to the no-save case. no protocol
changes, no scoring changes, no openssl bump, no on-the-wire
fingerprint changes. save-file md header is brand-free so the public
audit grep over the source stays at the existing 2 matches.
