Lot 252-300: 49 new teardowns — bench reaches 301 studies

Fills the 252-300 gap (301-triple-rsi already existed), so the bench is now
a continuous 1..301. Theme: sentiment/alt-data, positioning & flows, macro
folk indices, collectibles, weather & cosmos, new calendar/holidays, new
crypto, and cultural/sport event studies.

Verdicts for the lot: 2 Real (287 Easter-Effect = pre-holiday effect, the
lot's only Fragile; 291 Doge-Tweets, Mirage), 15 Weak, 32 None — all but one
Mirage on tradability. Bench score now 36 Real / 118 Weak / 146 None and
3 Investable / 62 Fragile / 235 Mirage across 300 stamped (study 14 pre-reg).

Each study ships the two executed notebooks, offline/deterministic module +
tests, docs/references + results. README table, tests.yml, docs/bench.md
families & score, and docs/bench.json + bench_map.png all synced to 301.
Gate: 301 complete, 0 failures.
