Fix PyInstaller cache hash mismatch by excluding build/dist directories

The compute_source_hash() function was including files from the build/
directory (generated by PyInstaller during the same run), causing the hash
computed at check time (before build/) to differ from the hash at save time
(after build/ exists). This made the cache always miss.

Fix: exclude build/, dist/, and __pycache__/ from the hash computation.
These are all build artifacts that don't affect the PyInstaller input.
