bug: _confirm_install_r_packages only catches EOFError, not BrokenPipeError

[MitchellAcoustics]

Description

In _confirm_install_r_packages() (src/soundscapy/r_wrapper/_r_wrapper.py), the try/except EOFError block only catches EOFError from input(). If print() raises BrokenPipeError (e.g. in a redirected-stdout environment like python -c "..." | head), the exception propagates uncaught through the dependency-check path, crashing what should be a graceful "should we install?" prompt.

Reproduction

python -c "import soundscapy.spi" | head -1
# BrokenPipeError propagates from print() inside _confirm_install_r_packages

Fix

Broaden the caught exception to cover OSError (which BrokenPipeError is a subclass of):

try:
    print(...)
    response = input("Install them now via soundscapy? [y/N] ").strip().lower()
except (EOFError, OSError):
    pass
else:
    return response in ("y", "yes")

Notes

• Found during code review of PR fix: R wrapper cleanup, DataFrame mutation bug, test coverage and docs #127 but left unfixed as unconfirmed/low-priority
• Only reachable interactively (when sys.stdin.isatty() is True), which limits the blast radius
• The SOUNDSCAPY_AUTO_INSTALL_R env var bypasses this path entirely for CI/scripts
