The shared with_shutdown_flag helper, and the AtomicBool/Arc/
install_signal_handler imports it uses, only exist when at least one
applet feature (client, server, tui) is enabled. Gate them accordingly
instead of leaving them unconditionally compiled, which broke
`--no-default-features` workspace CI under -D warnings (unused
function/dead-code).
Also correct the README installation section: tui is already part of
the default feature set, so an ordinary `cargo install` already
produces irtt-tui alongside the other three binaries. Document a
lightweight `--no-default-features --features client` install instead
of the previous (incorrect) framing of tui as an opt-in extra, and fix
the same gap in the binaries/features table.
Rename the application Cargo package from irtt-cli to irtt-rs
(crates/irtt-cli -> crates/irtt-app), and hard-rename its scriptable
client binary from irtt-cli to irtt-client, now that the application
also ships a first-class server and the old name reads as an umbrella
CLI for both roles.
Give each dedicated binary (irtt-client, irtt-tui, irtt-server) its
own entry point instead of funneling through the multicall
dispatcher's argv0/subcommand logic, so a dedicated binary only links
the applet code for the role it implements and always runs that role
regardless of the name it's invoked or copied under. irtt-rs remains
the feature-selectable multicall dispatcher and is now the only binary
that inspects argv0 or subcommands.
Move future application releases to the irtt-rs/vX.Y.Z tag namespace
(regenerated via `dist generate`), and bump the application package to
0.6.0 as a breaking distribution change. Library crate versions are
unaffected.
