Release v4.180.2

Fixed

• Parsing a valid model no longer fails with a regular-expression timeout when the host is busy. The compiler's own patterns now run on .NET's linear-time regular expression engine with no wall-clock timeout, so they stay safe against hostile input without depending on how fast the machine is. Parsing the samples is also about twice as fast. (#796)
• Import globs are matched folder by folder without regular expressions, so a glob with many wildcards or ** segments can no longer exhaust memory or the stack. (#796)
