fix(enforce): hole 7 — ремонт инфраструктуры requires justification line

Brain-retro #5 candidate C, hole 7: the 'ремонт инфраструктуры' phrase
suppressed ALL rule keys with no constraint. Now requires a 'ремонт: <what>'
line in the same prompt documenting the target.

enforce-override-vocab.json: added 'requires_justification: "ремонт:"' to
the entry.
enforce-hook-helpers.mjs findOverride(): honors requires_justification — when
set, the user prompt must contain '<prefix> <non-empty-text>' or the override
is rejected.
