Compiled-regex battery for lib/core/settings.py.

settings.py defines ~40 module-level *_REGEX patterns that drive WAF/error/
charset/IP/title detection. A bad edit to any one of them is a silent failure
(detection just stops firing). This compiles them all and pins the behavior of
the high-traffic detection patterns with positive + negative cases.
