perf(regex): eliminate per-call clone overhead in preg_* dispatch

regex::Regex::clone() does not share the underlying meta engine's
search-cache pool, so every fresh clone pays a ~10us warmup cost on
its first use. Two changes together eliminate this across nearly all
preg_* call sites:

- A php_regex! macro resolves PHP-style patterns to a per-call-site
  &'static regex::Regex (via regex-macro's LazyLock), applied at the
  majority of call sites throughout the codebase.
- Call sites still passing dynamic pattern strings go through
  PATTERN_CACHE, which now stores Arc<(Regex, bool)> and hands out
  Arc::clone()s instead of cloning the Regex itself.

PregPattern::resolve() returns a ResolvedPattern enum (Arc or
'static reference) rather than an owned Regex, so neither path ever
clones the Regex proper.
