+echo "Regenerate mise wrappers that still print mise's output on every run"
+
+# omarchy-mise-install passes --quiet to `mise use -g`, but wrappers written
+# before that gained the flag still run the loud form on every invocation, and
+# `mise use -g` writes its confirmation to stdout:
+#
+#   $ gh auth status 2>/dev/null | head -1
+#   mise ~/.config/mise/config.toml tools: gh@2.100.0
+#
+# That corrupts anything reading one of these tools through a pipe. The sharpest
+# case is git: with credential.https://github.com.helper set to
+# `!gh auth git-credential`, the banner becomes the first line of the credential
+# protocol and every HTTPS push fails with "invalid credential line" followed by
+# "could not read Username".
+#
+# Only the shape omarchy-mise-install writes today is matched. The generation
+# before it (`exec "<path>" "$@"`) was already converted by 1784909971.sh, and
+# migrations are strictly ordered, so it cannot still be on disk here. A wrapper
+# whose arguments were %q-escaped rather than double-quoted is left alone as
+# well: skipping one is a stale wrapper, misparsing one is a broken command.
