-p now connects a real capture stream via the pipewire crate and pushes
mono f32 straight into the render channel from the RT process callback,
instead of spawning pw-record and parsing its s16 stdout. It captures the
default sink monitor (what you hear), negotiates F32 at the graph's native
rate/channels, and takes a --latency <frames> quantum hint (default 256)
so you can trade CPU/xrun-risk for lower latency.
libpipewire becomes a build+runtime dependency: CI installs the dev
headers + clang, and the PKGBUILD depends on libpipewire.

Move PCM decoding into a producer thread that feeds an mpsc channel,
letting the render loop drain samples non-blockingly each frame. Add a
frame-aligned sleep via event::poll to replace the implicit CPU yield
that the old blocking read provided. Also replace powf(0.5) with sqrt().

ncurses-rs is broken on Arch Linux ARM (missing TRUE constant in
generated bindings) and the git HEAD version breaks Ubuntu too.
crossterm is pure Rust with no C dependency, eliminating the issue
on all platforms.
