dualfroz dea7d75d42 fix(dispatcher): surface preg_match() engine failures instead of treating them as no-match ...

All dispatcher strategies checked preg_match() results with `!== 1`,
which conflates a genuine no-match (0) with a PCRE engine failure
(false), e.g. PREG_BACKTRACK_LIMIT_ERROR from a catastrophically
backtracking route pattern. Because dynamic routes for the same
method are combined into shared regex chunks, one such route could
make the preg_match() call for the whole chunk fail, silently
turning an unrelated, cheap route in that chunk into a spurious
NOT_FOUND.

Add a shared matchRoute() helper on RegexBasedAbstract that calls
preg_match() and throws a RuntimeException (including
preg_last_error_msg()) when it returns false, while preserving the
existing 0/1 no-match/match behavior. Update GroupCountBased,
GroupPosBased, CharCountBased and MarkBased to use it.

Fixes #167
