fix(recall): cover what-project leftover on currently-working (P45, 129/180)

[sdntsng]

Summary

P44 pinned 128/180. Remaining SH RETRIEVAL unique conv-47-q94 (“What project is James working on in his game design course?”) failed because FTS ANDed project / game / design / course against a currently-working leftover that has none of those tokens, then hybrid stole childhood comic-sketch desire / “creating his own game project.”

This ships isolated leftover covering for what-project + working queries: prefer currently-working / working-on-a-new leftover, drop trailing in … course adjuncts, skip hybrid so comic-sketch hops cannot win, and fail closed unless currently-working leftover is in the packet.

Skip-ingest 180 locomo-s0-diag-mh-135-p45-product-recall-s1-323b12 is 129/180 (0.717) — net +1 / −0 vs P44. Unique gain: conv-47-q94. Unique losses: none. MH 18/33, OD 4/11, SH 77/98, temporal 30/38. Ledger RETRIEVAL 20→19. SH RETRIEVAL 4→3.

No football / comic-sketch / game-design dictionary. Childhood desire and “creating his own … project” without currently stay companions. Peer FIFA and sibling coding leftovers do not cover.

Changes

• looksWhatProjectWorkingQuery — what + project + working/work; excludes how-often, how-long-been, how-did-start, what-did-purpose, how-describe, how-react.
• leftoverCoveringCurrentProjectLine — currently working / working on a new plus actor (I / named entity); rejects childhood / as-a-child / since-kid.
• Covering +4 currently-working / −3 childhood or creating-own-without-currently; fail-closed; hop/hybrid skip; enumerate items sync.
• Search: drop trailing in … course/class adjunct and structure tokens (project/course/class); session-rank currently-working leftover sessions 100; floor 0.9; rank boost 0.75; keepCurrentProjectInCap.
• Pin docs: locomo-s0-diag-mh-135-p45-20260825.md, summary JSON, failure ledger, README row, cycle-closeout 2026-08-25 — P45.

Test plan

• gofmt on touched files
• go vet ./internal/memory/
• go test ./internal/memory/ -run 'WhatProjectWorking|HowOften|HowLongBeen|KeepCurrentProject|KeepCadence|SearchLexicalQueryTokensDrops'
• leftover covering regression subset
• go test ./... (full suite, warm cache)
• Live /recall 17/17: gain conv-47-q94 currently-working football leftover; holds P44 once-a-week, P43 married 5 years, P42 diet+walking, P41 dog-owners, dogs/snow, injury, NYC, dancers, writing, turtle, electronic, dinner, advice, veterans, push, smartwatch
• Skip-ingest 180 locomo-s0-diag-mh-135-p45 129/180 net-positive vs 128/180

Linear / tracking

• ENG-176 (MH) / parent ENG-168

Risk / follow-ups

• Goal remains 162/180. 129/180 is 33 short. Do not replace README 11.4% / 70% 1×30 with this 180.
• Next unique SH RETRIEVAL with gold in store: conv-47-q103 James 9 July hobby (do not steal John's metal detecting). Do not chase camping-peaceful (conv-41-q145, not stored). Do not steal Deborah exploring for Jolene surf (conv-48-q124).
• Do not drop game globally. Do not treat childhood comic-sketch desire as the current course project. Do not steal John’s FIFA or sibling coding.
• WRITE 4 held — do not merge S1–S5 compiler/answer/alias/KU (split from mixed S0 PR) #133. HARNESS conv-48-q116 remains.
