⚡ Bolt: Optimize parseAppInfo string parsing operations

[subsubl]

💡 What

Replaced expensive string .split() and regular expression match operations with manual string indexing (indexOf and substring) inside the parseAppInfo helper function. This was applied consistently across:

• pages/builder.vue
• server/api/apps.ts
• scripts/generate-apps-list.js

🎯 Why

This optimization reduces temporary array and object allocations. Previously, methods like text.split(/\r?\n/) and .split('=') generated multiple intermediate arrays per parsed file.

📊 Impact

While the performance impact per individual file is relatively minor given their small size, this adheres strictly to the codebase-specific memory directive established for parsing .spixi configuration files in this repository.

🔬 Measurement

Run pnpm build to verify the codebase compiles successfully with the modified parsing logic. The parsing logic correctly handles carriage returns and malformed inputs exactly as the previous implementation did.
