Windows fixes: installer archive layout, coding-tool argument quoting, e2e CRLF - #126

The Windows archive unpacks to wally-<platform>\bin, the root that package-wally-windows.ps1 stages and that install.sh and verify-release-assets.py expect. install.ps1 looked for the asset stem instead (wally-<version>-windows-x86_64\bin), so every install stopped with "does not have the layout this installer expects". Resolve wally-<platform>\bin, keeping the versioned spelling as a fallback.
Windows Python writes text-mode stdout as CRLF, so ids read from `models list --json` carried a trailing \r and wally rejected them as unknown models. Only reached on machines with a downloaded model.
_spawnvp joins argv with bare spaces, so any argument containing a space reached claude-code, hermes, openclaw and dsh split into separate words: `wally hermes -z "fix the tests"` failed with "'the' is not a hermes command", and Claude Code received only the first word of a prompt. opencode already quoted its arguments; move that QuoteWindowsArg into the shared harness code and apply it in Spawn, with a unit test for spaces, embedded quotes and trailing backslashes.

In `@src/harness/harness.cpp`:
- Line 367: Update the Windows target-launch flow around QuoteWindowsArg and
_spawnvp to explicitly handle resolved .cmd and .bat targets before
CreateProcess; either invoke %COMSPEC% using a command-processor-safe argument
builder or reject these targets with a clear error. Add a Windows regression
test covering the selected behavior.

Summary
Three Windows fixes: the PowerShell installer, argument passing to coding tools, and the modality e2e script.
1.
install.ps1: resolve the archive'swally-<platform>rootThe Windows archive unpacks to
wally-<platform>\bin. That is the rootpackage-wally-windows.ps1stages, and the oneinstall.shandverify-release-assets.pyexpect.install.ps1looked for the asset stem instead (wally-<version>-windows-x86_64\bin), so every Windows install stopped here:The installer now resolves
wally-<platform>\binand keeps the versioned spelling as a fallback.2. Harness: quote arguments when launching coding tools
_spawnvpjoins argv with bare spaces. Any argument containing a space therefore reachedclaude-code,hermes,openclawanddshas separate words:wally hermes -z "fix the tests"failed with'the' is not a hermes command.opencode.cppalready had a correctQuoteWindowsArg. This moves it into the shared harness code, applies it inSpawn, and adds a unit test covering spaces, embedded quotes, trailing backslashes and empty arguments.3.
e2e-modalities.sh: strip CR from model idsWindows Python writes text-mode stdout as CRLF. Ids read from
models list --jsontherefore carried a trailing\r, and wally rejected them as unknown models. This only happens on machines that have a downloaded model.Testing
Tested on Windows 10 x64 with a local MSVC 2022 build of this branch against the pinned kit.

Fixes three Windows-only issues: the PowerShell installer's archive layout check, argument handling when launching coding tools, and CRLF handling in the e2e-modalities script.
