ddidderr 61481eaf46 feat(client): add scoped interface metric override ...

Add a reversible IP interface metric boundary to `lanparty-client-route`. The
crate can now read an IPv4 or IPv6 interface metric snapshot and temporarily set
a manual interface metric with an RAII guard that restores the previous metric
and automatic-metric state on drop.

This prepares the TAP metric handling without wiring policy into the Windows
client yet. Default-route disabling is captured in snapshots for diagnostics and
future decisions, but this slice deliberately changes only `UseAutomaticMetric`
and `Metric`.

Test Plan:
- cargo fmt --check
- cargo test --workspace
- cargo clippy --workspace --all-targets -- -D warnings
- cargo check -p lanparty-client-route --target x86_64-pc-windows-msvc
- cargo clippy -p lanparty-client-route --target x86_64-pc-windows-msvc --all-targets -- -D warnings
- git diff --check
