Reworked all FILL-IN exercises + StackMachine lemmas with different proof structures (term-mode, constructor, congruence-lemma reuse). Full project builds (853 jobs).
Soundness (all 7), Completeness (all 5), and TotalCorrectness (wpIsWeakest + wpLemma base cases) reworked with term-mode proofs, constructor-based structures, and direct field access. Plus mul4Inj and Assertion.impl_self in Exercises. Full project builds (853 jobs).

I tried using different proof structures than the reference (meaning i used term-mode, constructor-based, congrurence-lemma reuse, direct field access and so on). It should only affect proofs while keeping every theory statement unchanged.
I re-proved:
All the marked exercises, eval exercises, equiv exercises, Transformation exercises, StackMachine lemmas;
Hoare metatheory: Soundness, Completeness, TotalCorrectness, and the respective exercises
The "lake build" passed with 853 jobs.
