fix: stop announcing a shadowed built-in on every command

[refsz]

Reported from real use of 0.2.1. A project with its own init task saw this before every command, including ones with nothing to do with init:

$ sputnik drush
Task 'init' in /project/tasks/InitTask.php shadows the built-in init command, which is no longer reachable
🛰  Sputnik v0.2.1 │ .sputnik.dist.neon │ dev

▸ drush · Run any drush command
  (1/2) > ddev exec vendor/bin/drush list

My mistake in #45: I treated both discovery messages as the same kind. They are not.

• A skipped task means something the author wrote does not work. That stays true on the next command, so it belongs in the output every time.
• A shadowed init works exactly as asked. Nothing is broken.

And the shadow notice has almost no audience: a project that has tasks has been initialised already, so the built-in scaffold being unreachable costs nothing. The one moment it helps is when someone is wondering why sputnik init no longer scaffolds — which is a -v question.

So discovery separates the two: getWarnings() prints always, getNotices() with -v. Both still travel through the container cache, since discovery only runs when that cache is cold.

The part I got wrong twice

The first attempt gated on isVerbose() inside Kernel::createApplication(), and the notice never appeared even with -v. Reason: Symfony parses -v in run(), which happens after the application is assembled — verbosity is simply not known at that point.

The E2E test caught it, which is why the reporting now lives in Application::doRun(), where the input has been parsed. That also moved the warnings there, so both come from one place.

Verified in the reporting project

sputnik list             (silent)
sputnik list -v          Task 'init' in .../InitTask.php shadows the built-in init command

And the counter-check that blocked names stay loud — a temporary task named list in the same project:

sputnik list             Skipped task 'list' in .../ZzTmpList.php: the name is reserved
                         by a built-in command - rename the task or give it a group prefix

Still on every run. Temporary task removed afterwards.

Tests

• testShadowingIsANoticeNotAWarning — shadowing produces a notice and no warning
• testASkippedTaskStaysAWarning — the skip produces a warning and no notice
• E2E asserts the shadow line is absent by default and present with -v, so a future change cannot quietly put it back into every command
