Allow separating the method and pattern with [ \t]+, this matches the
stdlib change that was made in golang/go@7b583fd

The rationale is the same as the stdlib issue, it allows you to visually
line up patterns with variable-width methods:

  r.Handle("GET    /my-route", handler1)
  r.Handle("POST   /my-route", handler2)
  r.Handle("DELETE /my-route", handler3)

In general aligning ourselves with the stdlib brings less surprise for
end users.

This code predates the introduction of the reverseMethodMap.

Go 1.21 brings us the builtin min func and slices.Contains.

Go 1.22 brings us range over int and fixed for loop scoping.

We were also able to drop the build tags from the path value code and
inline the three-line function directly. This should still work on
tinygo as they claim to support Go 1.24.

Simplify server shutdown by replacing manual signal handling with `signal.NotifyContext`.

Fixes #1021.

This wasn't updated in either #969 or #1017 and is the first thing people read on pkg.go.dev.

The RouteHeaders middleware was missing a return statement after calling
next.ServeHTTP when the router had no routes configured. This caused the
next handler to be called twice - once in the empty check and again at
the end of the function.

Also adds comprehensive test coverage for the RouteHeaders middleware
and Pattern matching functionality.
