Subject: [PATCH] fix(cli): gate Linux-only self-update symbols behind
 cfg(unix)

The CLI self-update module installs only on Linux: install_archive has a
#[cfg(not(unix))] stub twin and every consumer of GzDecoder, Cursor,
Archive, DEPRECATION_WARNING, find_package_dir, validate_entrypoint_pair,
validate_plugin_host_resources and copy_plugin_host_resources lives in the
#[cfg(unix)] install path. On Windows builds rustc therefore reports these
symbols as unused/dead code (unused import `flate2::read::GzDecoder`,
`std::io::Cursor`, `tar::Archive`, unused const `DEPRECATION_WARNING`,
dead functions `find_package_dir`, `validate_entrypoint_pair`,
`validate_plugin_host_resources`, `copy_plugin_host_resources` in the
upstream CI build logs).

Gate exactly these eight symbols with #[cfg(unix)] so Windows builds no
longer emit the warnings while the Linux install path stays unchanged.

Adopted-from: taiji 80820986b (import/const gate hunks) and taiji
931acc0c6 (validate/copy_plugin_host_resources gate hunks).

Test: cargo check --locked -p bitfun-cli on Windows, exit 0, no remaining
warnings for the self_update module.
AI: implemented with AI assistance, lightly tested (cargo check only).
