Fix Acer Aspire Go 15 internal keyboard dropout

[baseman70]

Summary

On the Acer Aspire Go 15 (AG15-42P, Ryzen 7 7730U), the internal keyboard drops out ~5 seconds post-boot under both Linux and Linux-LTS kernels. The trackpad and external USB keyboards continue functioning, but keystrokes on the built-in keyboard stop registering due to an i8042 / atkbd ACPI conflict with acer-wmi.

Adding i8042.reset atkbd.reset acpi_osi=Linux to the kernel command line resolves the conflict and keeps the internal keyboard responsive.

Implementation Details

1. Hardware Detector: Added bin/omarchy-hw-acer-aspire-go-15 checking sys_vendor for Acer and matching Aspire AG15-42P / Aspire Go 15 via omarchy-hw-match. Uses OMARCHY_DMI_SYS_VENDOR for testability.
2. Hardware Leaf: Added install/hardware/acer/fix-aspire-keyboard.sh to install /etc/limine-entry-tool.d/acer-aspire-keyboard.conf with KERNEL_CMDLINE[default]+=" i8042.reset atkbd.reset acpi_osi=Linux".
3. Hardware Orchestration: Registered the leaf in install/hardware/all.sh.
4. Migration: Added migrations/1788707260.sh to apply the drop-in, rebuild Limine boot configuration via limine-update / limine-mkinitcpio, and mark reboot-required if the parameters are not already active in /proc/cmdline.
5. Automated Tests: Added test/shell.d/acer-aspire-keyboard-test.sh covering detection, case-insensitivity, fail-closed behavior on missing attributes, leaf drop-in creation and idempotency, migration limine-mkinitcpio fallback, failure propagation, and reboot-request gating.

Verification

• Tested locally on physical Acer Aspire Go 15 AG15-42P hardware (running Omarchy 4.0.2 with kernel 7.1.9): internal keyboard is fully operational.
• Verified ./test/cli passes all 70 checks (including commands --check).
• Verified ./test/shell.d/acer-aspire-keyboard-test.sh passes all 17 test assertions.

[baseman70]

Added 5 additional automated test cases to test/shell.d/acer-aspire-keyboard-test.sh (expanding the suite to 17 assertions, all passing):

• Missing attribute fail-closed: Verified omarchy-hw-acer-aspire-go-15 returns non-zero when /sys/class/dmi/id/sys_vendor is absent.
• Case-insensitivity: Verified vendor matching succeeds across casing variants (Acer / ACER).
• Leaf idempotency: Verified running fix-aspire-keyboard.sh repeatedly does not duplicate configuration lines or corrupt the drop-in.
• Bootloader fallback: Verified migration falls back to limine-mkinitcpio when limine-update is absent.
• Failure propagation & retry semantics: Verified that if the bootloader rebuild command fails, the migration halts and leaves reboot-required unset so the migration remains pending to retry on the next update.

All 17 checks in test/shell.d/acer-aspire-keyboard-test.sh and all 70 checks in test/cli pass.
