Yongqi ZhuoandClaude Fable 5 2169b925ae [BugFix] Always vectorize T.Parallel loops (#3121) ...

* [BugFix] Always vectorize `T.Parallel` loops

* Fix CI failures

* Restore always-vectorize accidentally reverted by the CI-fix commit

f447919b captured a transient working-tree state from a concurrent
baseline-vs-patched benchmark flip, reverting the gate removal in src/
while keeping the new-policy tests: CI then ran the old gated compiler
against them (scalar var-loop -> no float2; positional if/for check
broken by the copy loops the larger tile introduces).

Bring back the parameter-less LowerParallelLoop and rewrite the issue
1734 assertion as containment: the guarded loop must sit inside the
hoisted if block, which holds on both sm90 and sm100 regardless of how
many copy loops precede it.
