test(windows): run the Windows code under Wine; theme preview parity

Windows was previously only compile-checked. With Wine 11 (staging) and mingw available, scripts/windows-wine-test.sh (`just test-windows-wine`) builds expat/FreeType/fontconfig for mingw under target/wine-deps and runs the test suites of ghostty-vt, unicode, datastruct, input, os, config, terminal, crash, termio and cli under Wine (~2,700 tests). New termio/tests/exec_windows.rs drives real cmd.exe children over ConPTY through Termio (output, exit codes, typing, 120 KiB writes, stop, start failure). Fixes found: Windows paths from fs::canonicalize leaked the \\?\ prefix (new ghostty_os::path::realpath strips it like Zig); ghostty-font compiles hb-ft for bundled HarfBuzz on Windows; ~25 tests had Unix assumptions. Wine limitations are ignored with reasons (ResizePseudoConsole stub, no POSIX rename over existing files) - docs/rewrite/notes/windows-wine.md. +list-themes preview parity (former KNOWN_DIFFERENCES rows 5-9): the search box ports vaxis TextInput (word navigation and editing bindings, grapheme-wise editing), ASCII-only case folding, light initial colors until terminal reports arrive (no COLORFGBG), and load errors end the preview with exit 1; PTY tests compare with /usr/bin/ghostty. Test Plan: - just test-windows-wine - cargo test -p ghostty-cli --test list_themes_pty - cargo test --workspace --no-fail-fast (3601 passed)

+# Run the Windows test suites under Wine (x86_64-pc-windows-gnu + mingw-w64).
+#
+# Usage: scripts/windows-wine-test.sh [cargo test args, default: the core crates]
+#
+# First run builds expat + FreeType + fontconfig for mingw into
+# target/wine-deps/prefix (like Ghostty, from source; needs network for the
+# expat tarball unless EXPAT_TARBALL points at one, and the fontconfig source
+# from the zig package cache or FONTCONFIG_SRC). A dedicated WINEPREFIX lives in
+# target/wine-prefix. Headless: no display is needed for console tests.
+# See docs/rewrite/notes/windows-wine.md.
