fix(open-in-apps): Improve Windows compatibility and command handling

[anglox]

This PR improves cross-platform reliability of the “Open in App” system, with a focus on fixing Windows execution issues and aligning command resolution behavior across platforms.

• Unix-only command -v and Windows-compatible where
• Updated quoting logic to be platform-aware:
  • POSIX: single-quoted shell escaping
  • Windows: double-quoted escaping
• Removed Windows start "" wrappers in favor of direct executable calls
• Zed integration improvements
  • Added Windows support for Zed launch commands
  • Marked Zed as supporting remote workflows
  • Added zed://ssh/... scheme handling for remote SSH paths

Issues addressed:

1. No tools detected on Windows even though I have some of them
2. Opening a detected tool on Windows spawns redundant shell

Greptile Summary

This PR improves Windows compatibility for the "Open in App" feature by replacing command -v with platform-conditional detection (where on Windows, command -v on POSIX), removing redundant start "" shell wrappers, and adding platform-aware path quoting. It also adds Zed Windows support and wires Zed into the remote SSH URL builder.

• Platform detection: checkCommand now uses where on win32 and command -v elsewhere, fixing the breakage on Windows where command -v is not available.
• Quoting: The quoted() helper is now platform-aware — POSIX single-quote escaping on non-Windows, CMD-style "" double-quote escaping on Windows.
• Zed remote: buildRemoteEditorUrl gained a 'zed' switch arm emitting zed://ssh/... URLs, and openInRemote now routes Zed through that builder (previously fell through to the "not yet implemented" error).

Confidence Score: 5/5

Safe to merge — all previously identified issues are addressed and no new defects were found.

The conditional where/command -v split correctly fixes Windows app detection without breaking macOS or Linux. The CMD-style "" quoting is the right approach for cmd.exe. Removing start "" is appropriate since the Electron main process has no terminal window to detach from, and the CLI tools being invoked (code, cursor, etc.) return promptly on their own. The Zed remote SSH path is now fully wired end-to-end: supportsRemote: true → openInRemote branch → buildRemoteEditorUrl 'zed' arm.

No files require special attention.

Important Files Changed

Filename	Overview
src/main/core/app/utils.ts	Adds platform-conditional command detection: where on Windows, command -v on POSIX. Correct and minimal — where.exe is always available in System32 on Windows, and the callback only checks the exit code so uncaptured stdout from where is harmless.
src/main/core/app/service.ts	Adds 'zed' to the remote-SSH URL-builder branch (fixing the previous "not yet implemented" fallthrough) and introduces platform-aware quoted() — POSIX single-quote escaping vs CMD-style "" double-quote escaping on Windows.
src/main/utils/remoteOpenIn.ts	Extends RemoteEditorScheme with 'zed' and adds a switch arm in buildRemoteEditorUrl that emits zed://ssh/<authority>/<path> rather than the VS Code vscode-remote scheme.
src/shared/openInApps.ts	Removes start "" <app> wrappers from all Windows openCommands entries, marks Zed as supportsRemote: true, and adds a win32 platform block for Zed.
