findOverride/findOverrideAttempt/loadOverrideVocab become permanent stubs returning null/null/empty.
Non-deleted hooks (verify-before-push, tdd-gate, memory-coverage, branch-switch) still import these
symbols and need them to compile; runtime always reports 'no override'.
Adapted 15 existing tests in enforce-hook-helpers.test.mjs and 7 in enforce-semgrep-security.test.mjs
that asserted old vocab behaviour; all now assert stub behaviour (null/empty).
1824/1824 vitest tools GREEN.
Stream G of router-gate v4 deployment.
