fix(tui): preserve quotes in Windows status line commands

[zhuyuy]

Related Issue

Resolves #2332

Problem

On Windows, status_line.command is passed to cmd.exe /d /s /c as one argv element. Node/libuv escapes embedded double quotes while serializing that argument, so commands that quote an executable or a path arrive at cmd.exe with literal backslashes and silently produce no status line output.

What changed

• Wrap the Windows command in the outer quote pair required by cmd /s /c and enable windowsVerbatimArguments, preserving the command's nested quotes.
• Keep the existing POSIX sh -c path unchanged.
• Add a Windows-only regression test that invokes the current Node executable through the real status-line spawn path with quoted arguments.
• Add a patch changeset for @moonshot-ai/kimi-code.

Validation

• Windows 11 10.0.26100, PowerShell 7.6.3, code page 936
• Node.js 24.15.0, pnpm 10.33.0
• Focused footer status-line tests: 17 passed
• @moonshot-ai/kimi-code TypeScript check: passed
• Type-aware Oxlint on the changed source and test: 0 warnings, 0 errors
• changeset status --since=origin/main: patch bump detected
• Independent complete-diff review: No findings.
• Internal-identifier audit: no private paths, accounts, endpoints, or environment-specific identifiers found

No documentation update is needed: the existing [status_line].command documentation already describes the intended command contract, and this change restores that documented behavior on Windows without changing configuration or usage.

Give the Windows quote test a generous timeout

On a busy Windows CI runner, this launches both cmd.exe and a fresh Node process but leaves timeoutMs at the production default of 300 ms. If process startup exceeds that deadline, runStatusLineCommand returns null, so the regression test can fail even when quote handling is correct. Pass a generous explicit timeout here to isolate the quoting contract; timeout behavior already has separate coverage.
