cb psql: SIGWINCH and terminal size are not propagated, input wraps wrong

TL;DR

Upgrade to 3.5.1 or later and the resize handling works. The maintainer reproduced it, identified the cause, and fixed it in v3.5.1.

Steps

1. A colleague quit using cb psql because of overwrite-style editing glitches: after resizing the terminal, typed input wrapped back to the start of the line. I could reproduce it reliably by expanding a terminal to full screen, shrinking it, and typing. SIGWINCH wasnt being propagated, so cb psql had the wrong terminal size. The maintainer reproduced it, identified the cause, and fixed it in v3.5.1. Closed May 2024.
2. cb psql wasnt propagating SIGWINCH, so after a terminal resize it kept the old size and mangled line wrapping. The maintainer reproduced it and shipped the fix in v3.5.1. Upgrade to 3.5.1 or later and the resize handling works. The reporter confirmed the fix, so theres no separate workaround needed.
