Merge PR #1 from mrexodia: Windows support and auto-refresh on events

https://github.com/blasty/ida-tui/pull/1 — from the ida-nexus (né
ida-codemode) maintainer: kitty-graphics fallback for platforms without
termios, Ctrl+R view refresh, typed remote operations through ida_nexus
RemoteModule, live auto-refresh from other clients' IDB events (upstream
item 7), discard-without-save (item 6), and the ida-nexus 0.7.0 rename.

tests/test_kittygfx.py is the union of both sides' files: our escape-
construction checks plus the PR's cross-platform fallback checks.
