Removes the now-unreferenced repair-only machinery left behind after
Stage 2 (1/3) neutralized the application:
- _v2_prompt_repair_text_allowed
- _v2_emphasized_prompt
- _v2_repair_prompt_for_missing_axes and the repair-candidate helpers
- perfect_repairs / rejected_repairs storage + perfect-repair eviction
note in the intent-family learn path
Shared helpers still used by intent-alignment (e.g. _v2_repair_intent_roots,
_v2_repair_candidate_matches_intent, _v2_prompt_contains_text) are kept, as
is the repair_feedback / active_repair_axes "what's missing" signal the
advisor reads.
Deletes the 11 category-alignment tests that exercised the removed methods
directly. No new test failures (the 10/31 remaining are pre-existing env
failures from missing server/comfy modules).
