fix: correctly surface unexpected evaluation errors

Browse source 
Previously, all errors in evaluation were completely swallowed except for
`XRefError`. This caused unexpected errors (e.g., BigInt conversion errors
or extension bugs) to result in a silently dead sheet.

This updates the `evaluateDocument` catch block to:
1. Continue surfacing `XRefError` (no console warning).
2. Continue silently ignoring expected `EvalError` instances.
3. Surface all other unexpected errors to the user via `lineError` and log
   them to the console, making debugging easier without crashing the application.
