Subject: [PATCH] Deprecate projectvar (V_delta, V_epsilon); file
 stimulus_approach under stimulus topic

- projectvar moved to deprecated/ in V_delta and V_epsilon (maturity_level
  and index.json tier/path updated). Deprecating it in V_epsilon as well as
  V_delta keeps the newest active set consistent.
- V_epsilon topics.json: stimulus_approach placed under the "stimulus"
  topic (it was previously uncategorized); projectvar added to the
  deprecated bucket.

V_gamma is intentionally untouched: it is a flat, index-less set whose
meta-schema maturity enum has no "deprecated" value, so it has no
deprecation mechanism (and no stimulus_approach class or topics.json).
