S2: recover food-set and charity-beneficiary lists (P61 144/180)

[sdntsng]

Summary

Product /recall recovers beneficiary organization sets for who/which beneficiary questions. Frozen skip-ingest store already had John's raise-for objects (dog shelter, homeless, children's hospital); leftover covering was answering with the CS:GO tournament slogan.

Skip-ingest 180 on this SHA: 144/180 vs P59 143/180. Unique CORRECT +1 (conv-47-q22). Unique leftover losses none. MH 24/33, OD 4/11, SH 85/98, temporal 31/38.

This is generic S2 enumerate, not leftover covering and not a LoCoMo gold dictionary. Food-set work on this branch did not flip the 180 (judge completeness + WRITE-missing gold); p60/p60b 143/180 are not pins.

90% on this 180 is 162/180. Public LoCoMo n=1540 is still 11.4%. Do not treat 144/180 as 90% or as beating Mem0. README published-% / 1×30 70% are not replaced.

Changes

• looksBeneficiarySetQuery — who/which/what + beneficiaries/beneficiary.
• recoverBeneficiarySlots / beneficiaryObjectsFromContent — raise/for-cues; thin-stop charity/CS:GO/tournament; cap 6.
• Recovered slots replace the named person's affiliation hop.
• Enumerate: no dual-entity join; lock to affiliation hops.
• leftoverCoveringKeepTypedAnswer keeps a ≥2 affiliation join.
• Pin docs: P61 144/180 closeout + benchmarks README row.

Test plan

• gofmt on touched files
• go vet ./internal/memory/ ./cmd/api ./cmd/worker
• go test ./internal/memory/ (23.5s, green)
• Live probe conv-47-q22: dog shelter, homeless, children's hospital (not CS:GO); P59/P60 holds (food q18, soda/candy, Audrey collars, James tricks, Maria dogs, Jolene snakes, dinner leftover)
• Skip-ingest 180 locomo-s0-diag-mh-135-p61-product-recall-s1-02435b 144/180, unique +1/−0 vs P59
• Pin docs; FF origin/dev (not main)

Linear / tracking

• ENG-176 (MH) / parent ENG-168

Risk / follow-ups

• Food-set q18/q37 remain judge-incomplete (WRITE-missing gold). Do not fish those further on skip-ingest.
• Next S2: community participation (conv-26-q39) and who-told (conv-49-q78) if gold is in the frozen store.
• Do not merge leftover-covering PRs S1–S5 compiler/answer/alias/KU (split from mixed S0 PR) #133, S0–S5 SOTA execution increments (stratified harness + compiler/answer/hop/LME) #131, fix(recall): instrument-purpose leftover covering over help flood #143, P29: demote single-token attended compiler echoes (ranking only) #145.
• Do not FF main.
