Moderate signal

editorial:auto 10d

Release v0.3.0 of Rmux builds binaries with Fat LTO and stripped symbols for smaller optimized builds while fixing multiple tmux‑compatible runtime issues.

Why it matters: Smaller, faster binaries (Fat LTO, codegen-units=1) improve deployment efficiency; bugfixes resolve key‑binding, copy‑mode, control‑mode, command parsing, and split‑window problems affecting everyday workflows.
