`display_path_with_home` joined the `~` prefix with `MAIN_SEPARATOR_STR`
but called `rest.display()` for the suffix, which preserves whatever
separators the input carried. On Windows that produced mixed-separator
output like `~\projects/foo` for any path that came in with forward
slashes — visible in the tests that #506 added to lock down the
contract (the tests passed locally on Unix but failed on the
windows-latest CI runner).
Walk `rest.components()` and join each `Normal` component with
`MAIN_SEPARATOR_STR`. Pure-Rust, no extra deps, behavior is
byte-identical on Unix because the input separator was already `/`.
Verified locally:
- `cargo test -p deepseek-tui --locked display_path` ✓ (5 passed)
