Subject: [PATCH] Canonical CI cleanup: TagBot thin-caller + downgrade-caller
 cleanup

Replace inlined JuliaRegistries/TagBot with the canonical SciML/.github
tagbot.yml@v1 thin caller. Remove the hand-listed stdlib skip input from
the downgrade caller (now auto-populated centrally) and set the downgrade
Julia floor to the lts alias.
