feat(open-in): add Xcode support

[arnestrickmann]

Summary

• Add Xcode as an "Open in" app option (macOS only)
• Uses bundle ID com.apple.dt.Xcode for detection and launching
• Hidden when Xcode is not installed (hideIfUnavailable: true)

Details

• Added xcode.png icon to ICON_PATHS
• Added Xcode app config with two open commands: open -b (by bundle ID) and open -a (by app name) as fallback
• macOS-only since Xcode is exclusive to Apple platforms

Greptile Summary

This PR adds Xcode as a macOS-only "Open In" option, following the established pattern used by other IDE and terminal entries in openInApps.ts. It registers the app via bundle ID detection (com.apple.dt.Xcode), adds a fallback open -a command, and includes a new icon asset.

Key observations:

• The config structure (bundle ID, hideIfUnavailable, platforms.darwin only) correctly matches how similar macOS-exclusive apps are registered.
• The open -b com.apple.dt.Xcode {{path}} invocation is consistent with iTerm2 and Ghostty; no --args needed since Xcode is document-based rather than CLI-arg-based.
• Xcode is inserted between terminal and warp in the list, placing an IDE in the middle of the terminal-emulator group. All other IDEs (IntelliJ IDEA, WebStorm, PyCharm, RustRover, Android Studio) live at the bottom of the array; moving Xcode there would keep the ordering consistent.

Confidence Score: 4/5

• PR is safe to merge; the only concern is a non-critical ordering inconsistency in the app list.
• The implementation is technically correct and follows established patterns. The single flagged issue is a style/UX concern (list placement) rather than a functional bug.
• No files require special attention beyond the ordering note in src/shared/openInApps.ts.

Important Files Changed

Filename	Overview
src/shared/openInApps.ts	Adds Xcode to ICON_PATHS and OPEN_IN_APPS; config is structurally correct but Xcode is placed between terminal emulators rather than with the IDE group at the bottom, and the open command passes a raw path where Xcode may not handle arbitrary directories meaningfully.
src/assets/images/xcode.png	New Xcode icon asset added as a PNG; binary file, no code issues.

Xcode placed in the terminal emulator group

The Xcode entry is inserted between terminal and warp, grouping it with terminal emulators (Warp, iTerm2, Ghostty). Xcode is an IDE, and all other IDEs in this file (IntelliJ IDEA, WebStorm, PyCharm, RustRover, Android Studio) are consistently grouped at the bottom of the list. Moving the entry there would keep the logical ordering intact for users browsing the "Open In" list.

(Place this block just before the intellij-idea entry rather than after terminal.)
