fix(ios): extract device UDID by id shape, not column position, in package-ios-zh.sh

[mvanhorn]

Summary

scripts/build/ios/package-ios-zh.sh --install now finds the target device by matching the identifier's shape instead of counting columns, so deploying to a device whose model name contains spaces works.

Why this matters

The install path read the device id with awk '/connected/{print $(NF-2); exit}' — the third field from the end of the row. xcrun devicectl list devices puts the model name last, so any multi-word model (iPad Pro 13-inch (M4), iPhone 15 Pro Max) shifts the columns and the script captures a fragment like 13-inch. Because that's non-empty it never falls through, and install fails with devicectl device install app --device 13-inch. The fallback was broken two more ways: grep -oE '[0-9A-F-]{36}' is uppercase-only (devicectl prints lowercase) and fixed at 36 chars, so it missed both 25-char modern physical UDIDs (00008020-001234567890ABCD) and 40-char legacy ones. The issue reporter diagnosed this and proposed a shape-matching regex.

Changes

Replaced the awk field-count and the broken fallback with one case-insensitive extraction on the connected row:

DEVICE_ID=$(xcrun devicectl list devices 2>/dev/null \
    | grep -iw 'connected' \
    | grep -ioE '([0-9a-f]{40}|[0-9a-f]{8}-[0-9a-f]{16}|[0-9a-f]{8}-([0-9a-f]{4}-){3}[0-9a-f]{12})' \
    | head -1)

It matches only valid id shapes (40-char hex, 8-16 modern, 8-4-4-4-12 UUID), so a model-name fragment can't be selected. One refinement over the proposed snippet: the state filter uses grep -iw so connected doesn't also match disconnected — otherwise a disconnected device's id would be picked and install would target an offline device. The empty-result error path and the devicectl device install call are unchanged.

Testing

devicectl needs real hardware, so I verified the extraction against representative fixture rows plus bash -n:

• bash -n scripts/build/ios/package-ios-zh.sh: passes
• Multi-word model + modern UDID (the reported case) → the UDID (old awk gave 13-inch)
• Lowercase 36-char CoreDevice UUID → the UUID (old fallback missed lowercase)
• 40-char legacy hex UDID → the full id
• Disconnected-only list → empty, so the existing "no connected device found" error fires
• Mixed connected + disconnected rows → the connected device's id
