[BUG] CLI crashes with raw traceback on non-UTF-8 .dmai files
评估
调研方向
Start in maithili_dsl/cli.py at run_dmai_file, where the file is read outside the try/except, and look at how existing errors print Maithili messages and pick exit codes. Wrap the read so a UnicodeDecodeError or OSError produces a friendly message and a non-zero exit. Done means a non-UTF-8 temp file in tests/test_cli.py gives the expected exit code with no traceback. Pull request #61 is already open against this issue, so check it before starting.

描述
File: maithili_dsl/cli.py (run_dmai_file)
The file is read outside the try/except, so a .dmai file that is not valid UTF-8 crashes the CLI with a raw Python traceback instead of a friendly Maithili error:
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte
(Verified against v0.3.0 with a UTF-16-encoded file.)
Fix: wrap the read in try/except (UnicodeDecodeError, OSError), print a Maithili error message (see existing style, e.g. ⚠️ त्रुटि: फाइल UTF-8 में नहि अछि।), and return a non-zero exit code (reuse EXIT_NOT_FOUND or add EXIT_BAD_ENCODING = 7 and document it).
Tests: tests/test_cli.py — write a non-UTF8 temp file, assert exit code and no traceback.
Good first issue: small, contained, and a nice tour of the CLI error-handling style.
