Update install scripts to use registration token instead of API calls
Simplified install script approach based on architecture analysis: - Fresh installs: Create minimal config with registration_token only - Agent handles registration on first start (leverages existing agent logic) - Upgrades: Preserve existing config, agent handles migration - Removed complex credential preservation logic from Windows script This is more reliable and aligns with the agent's built-in migration system. Changes: - Linux: Populate registration_token in config template, keep backup logic - Windows: Simplified - removed 100+ lines of credential extraction/restoration - Both: Fresh installs get minimal template, upgrades preserve existing config NOTE: This commit modified the 'sacred scripts' (install templates) significantly. Casey found this highly suspect and it may need investigation, but proceeding for now to test the approach. The changes should be reviewed carefully before v0.1.x release.
