Zig's standard std.http.Server has no routing DSL. Applications usually
branch on request.head.target and request.head.method after
receiveHead(), then call request.respond(...) or a handler function.

Whole-file detection gate, evaluated once per .zig file. String#matches?
(PCRE2 JIT) is faster than the naive String#includes? char scan, and
STD_IMPORT_RE folds the two-way OR into a single scan. Each matcher is
equivalent to the literal substring test it replaces.

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.
