The startup output was dominated by two upstream behaviours. Migrate
printed a bare count for every already-applied migration — a lone "1"
with no version, no explanation — through the standard logger, hence
stderr, which the launcher's `2>&1 |` renders as a red PowerShell error
block that looks like a failed migration. And the version-existence check
echoed one SELECT count(*) per version. Both replaced: a Warn-level
session for the check, and one summary line on stdout.
Console encoding needed more than [Console]::OutputEncoding: PowerShell
5.1 decodes child-process output by the console code page, so chcp 65001
goes with it.
The regression test capture was wrong twice and mutation testing caught
both. It captured only stdout while the bug wrote to stderr, and it
compared lines to "1" when the logger prefixes a timestamp, so the
assertion could never fail. It now captures the standard logger too and
matches with a pattern that allows the prefix — verified by reinstating
the bug and watching the test fail.
Not verified: the PowerShell edits, which need a Windows run.
