Fix jq parse error on parallel iOS commands (iscreenshot -a)

[vrbajiva]

Problem

Running iscreenshot -a (or other parallel iOS commands) prints:

jq: parse error: Invalid numeric literal at line 2, column 30

Screenshots still save, but the error is printed for every-but-one device.

Cause

All iOS commands share a single temp file for go-ios output:

# common_tools
TEMPORARY_FILE="/private/tmp/mobile-toolkit-cache"

iscreenshot -a runs screenshot "$ID" & per device concurrently. Each calls ios_device_info, which does go-ios info > "$TEMPORARY_FILE" and immediately reads it back with jq. With multiple devices, one job overwrites the file while another is mid-read → garbled/partial JSON → the jq parse error. Single-device runs never hit it (no concurrency).

Fix

ios_device_info now uses a per-device temp file keyed by the (unique) UDID, so concurrent jobs never collide:

local TEMPORARY_FILE="$TEMPORARY_FILE-${1//[^A-Za-z0-9]/_}"

• Callees (ios_check_pairing, ios_check_developer_image) inherit the value via bash dynamic scope, so the whole chain stays consistent.
• The file is cleaned up (rm -f) afterwards.
• Matches the existing per-invocation temp-file idiom already used in iinstall and irecord.

Testing

• shellcheck (with the CI-disabled rules SC1090/SC2207/SC2001/SC1091) reports no new findings vs. before the change.
• changelog.txt updated per CONTRIBUTING.
