Python's sqlite3.executescript() has a bug where trailing newlines after
the final semicolon create empty statements. When APSW's log_sqlite() is
enabled (via apswutils, imported by fastmigrate), these cause visible
"API called with NULL prepared statement" errors during interpreter shutdown.
- Strip trailing newlines from all 9 existing migration files
- Update migration template to end with semicolon, no trailing newline
- Document the requirement in CLAUDE.md
