fleetd #638: stop the verdict userinfo mask from crossing / or whitespace

mask_verdict_userinfo's character class [^@]* crossed a '/' or a space, so a
verdict line with a URI that has no userinfo plus a later @ (e.g. an email
address in diagnostic prose) had everything between them destroyed. Restrict
the class to [^@/[:space:]]* so the match stops at the end of the URI.

Adds the uncovered-direction test: a URI with no userinfo plus a later @ in
the same line must pass through byte for byte. Also drops the design-rationale
sentence from the helper's comment (now in the PR description).

+ * pinned, nothing proved either real caller ({@code Fleetd.main} and {@link ConfigRef#reload()})
+ * still invoked it — deleting the call site left the full suite green (1478/0/0/0). A follow-up
+ * measurement (same technique — remove one call site, run the suite, not read the code) found the
+ * SAME gap for all five of {@link FleetConfig}'s other validators at startup, and for four of the
+ * six inside {@link ConfigRef#reload()}. This is a class of gap, not one line's mistake: every one
+ * of those thirteen tests called the validator itself directly, never the real caller that was
+ * supposed to.
  *
- * <p>{@link #theSweepMechanismIsGenericNotHardcodedToFleetConfigsSixNames()} and its neighbours
- * prove that {@link FleetConfig#invokeAllValidators} runs each public, no-arg, void
- * {@code validateXxx()} method on its target. {@link #fleetConfigDeclaresExactlyTheseValidatorsToday()}
- * is the canary for the validator set. {@link #validateAllReachesEveryOneOfTodaysRealValidators()}
- * is the reachability check for that set.
+ * <p>The fix replaces the six individual {@code cfg.validateXxx()} calls at each of the two real
+ * call sites with one {@link FleetConfig#validateAll()}, which reaches every validator by
+ * reflection rather than by a hand-maintained list of names. A hand-maintained list of six names
+ * would have exactly the defect it replaces: the seventh validator someone adds next month has no
+ * reason to be added to it, and nothing would say so. This class proves TWO separate claims, and
+ * keeps them separate on purpose:
+ *
+ * <ol>
+ *   <li>{@link #theSweepMechanismIsGenericNotHardcodedToFleetConfigsSixNames()} and its neighbours
+ *       prove the reflective sweep itself ({@link FleetConfig#invokeAllValidators}) is a general
+ *       mechanism — it runs whatever public, no-arg, void {@code validateXxx()} methods a class
+ *       happens to declare today, including a class with more of them than {@link FleetConfig}
+ *       has right now. This is the proof that a future, real seventh validator on {@link
+ *       FleetConfig} would be swept automatically, without needing to add a real (unwanted)
+ *       seventh validator just to exercise the claim.</li>
+ *   <li>{@link #validateAllReachesEveryOneOfTodaysRealValidators()} proves {@link
+ *       FleetConfig#validateAll()} itself is wired to that same generic mechanism and genuinely
+ *       reaches every one of today's real validators — reusing the exact minimal failing
+ *       configurations {@code FleetConfigTest} already established for each one directly, plus a
+ *       dedicated fixture for {@link FleetConfig#validateLeadRollover()}, which no other test
+ *       drives through {@code validateAll()} — so a single call to {@code validateAll()} is shown
+ *       to reproduce every one of those failures.</li>
+ * </ol>
+ *
+ * <p>Together with the direct-{@code Fleetd.main}-invocation tests in {@code
+ * FleetdStartupValidationTest} (which prove the real startup call site still calls {@code
+ * validateAll()}) and the {@code ConfigRefTest} reload tests (which prove the same for {@link
+ * ConfigRef#reload()}), removing {@code cfg.validateAll();} from either real call site now fails
+ * a test in this module.
+ *
+ * <p><b>What is NOT pinned, measured rather than assumed.</b> Reverting {@link
+ * FleetConfig#validateAll()} to a hardcoded list of today's method calls leaves the whole
+ * suite green. Nothing ties {@code validateAll()} to
+ * the generic sweep — claim 1 proves {@link FleetConfig#invokeAllValidators} is generic, and claim
+ * 2 proves {@code validateAll()} reaches today's validators, and a hardcoded list satisfies both. So the
+ * reflective sweep is a convenience, not the guarantee. The guarantee is {@link
+ * #fleetConfigDeclaresExactlyTheseValidatorsToday()}: it fails the moment any validator is added
+ * or removed, which forces whoever changes the set to look at this file.
