fix(test): redact cwd path in ParsePlanRequest on Windows

The previous attempt unconditionally replaced `\\` with `\` on Windows
to unescape Debug-formatted paths, but this also collapsed the `\\?\`
verbatim prefix in Display-formatted paths used by other errors
(e.g. `ambiguous package name`), breaking those snapshots.

Instead, fix the root cause: format `cwd` with Display (`{cwd}`)
rather than Debug (`{cwd:?}`) in `ParsePlanRequest`. Display uses
`Path::display()` which emits raw backslashes on Windows, so the
existing raw `workspace_root_str` redaction works uniformly. Keep
the surrounding double quotes explicitly in the format string so
the existing `"<workspace>/"` snapshot stays exactly as-is.

Revert the test-side `\\` → `\` unescape now that it is no longer
needed and was breaking previously passing tests.
