Avoids the "paste the full output" friction. Every elway run now
writes its full streamed output to two files in addition to the
terminal:
/tmp/elway-last.log
always overwritten — the easy "what just happened" target
~/.cache/elway/runs/<ts>-<host>-<playbook>.log
timestamped permanent record; accumulates across runs
Implementation: small _Tee class wraps sys.stdout for the duration
of main() so all `print(...)` calls fan out to the real terminal +
both file handles. Subprocess output already goes through print()
via _stream_process, so the build/healthz/etc. text is captured.
ANSI color codes are kept in the file so colors are preserved in
log viewers that handle them (less -R, modern tail). Strip with
`sed 's/\x1b\[[0-9;]*m//g'` for paste-elsewhere.
New flags:
--log <path> override path; replaces both default destinations
--no-log terminal-only, skip both files
Path of the permanent log is printed at the top of every run so
you know where it landed without remembering the timestamp pattern.
