@vchuravy this isn't ready for code review. It's just a demo of the interface. Sorry, I should've been clearer up top. |

Run package precompilation in a background task, with a monitor task that
streams output and handles keyboard input. This enables users to detach
from precompilation (letting it continue silently) and reattach later.
Keyboard controls during precompilation:
- 'c' cancels all subprocesses (SIGKILL)
- 'd' detaches from monitoring (when detachable=true)
- 'i' sends a profiling signal (SIGINFO/SIGUSR1) for profile peek
- Ctrl-C interrupts subprocesses (SIGINT) and shows output
Signal broadcasting uses per-subprocess Channel{Int32} registered in
BACKGROUND_PRECOMPILE.signal_channels. The keyboard handler broadcasts
to all channels, and per-process tasks forward signals via kill().
Adds a detachable::Bool keyword to precompilepkgs, and background control
functions: monitor_background_precompile, stop_background_precompile,
is_precompiling_in_background.
The Pkg.jl side of this change is in JuliaLang/Pkg.jl#4602.
