Normalize renderer login preference for launchd

[VdustR]

TL;DR

Fixes device-verified Open at Login drift where the renderer plist received false while the bridge plist and persisted preference were true.

Follow-up for #51.

Cause

The installer passed 1 or 0 directly to plutil -bool. The bridge parser treated 1 as true, but plutil did not, leaving the two LaunchAgents inconsistent.

Changes

• Normalize 1/true to the plist boolean true.
• Normalize 0/false to the plist boolean false.
• Reject invalid preference values.
• Cover both mappings and the normalized plist write in script tests.

Verification

• PYTHONPATH=src python3 -m unittest tests.test_scripts
• bash -n scripts/install-renderer.sh
• git diff --check

Device evidence

Before this fix, the persisted preference was 1, bridge RunAtLoad was true, and renderer RunAtLoad was false after a successful upgrade. After merge, the target Mac will be reinstalled and both plist values read back.
