The compiler crashes with an unhandled ENAMETOOLONG error when compiling contracts with very long names, due to generated filenames exceeding filesystem limitations.

Minimal Example:

contract AAAAAAAAAAAAAAA... (extremely long name) {}

Observed Error:

Error: ENAMETOOLONG: name too long, open '/tmp/longname.tact_AAAAAAAAAA....fc'

Cause:
The compiler directly uses the contract name to generate filenames without checking the length, causing unhandled filesystem errors.

Expected Behavior:
The compiler should enforce a sensible maximum contract name length or gracefully handle filename generation to avoid crashing due to filesystem constraints.
