dart:io's HttpServer is Dart's built-in HTTP server surface. It has
no declarative router, so routes are usually guards over
HttpRequest.method and HttpRequest.uri.path inside an await for
or listen handler.

Regex.union("
HttpServer", "

Whole-file detection gate, evaluated once per .dart file. A precompiled
Regex.union (PCRE2 JIT) replaces the two OR-ed String#includes? scans
it used to run — provably equivalent since union auto-escapes each literal.

Instance methods
tech
Instance-side view of the same declaration. The per-file rescues live on
this base class, which has no way to name the analyzer that is running
inside them, so a skipped file could not be attributed to a tech.
Deriving it from analyzer_for keeps the name written exactly once.
