qa(warrant): #000003 land — anchor-class generalization (D6 → ✓)

Browse source 
Three new question-shape classes dispatched through warrant_check
alongside the existing relation + date anchors:

(1) Entity-list shape — `name X`, `list X`, `who are the members
    of X`. List-aware extractor `extract_entity_list_anchors`
    (multi-word phrases ∪ solo-cap individual names) so comma-
    separated entities each contribute. ANY-match semantics:
    demote-don't-reject when an extra entity from training-prior
    appears alongside grounded ones.

(2) Count shape — `how many X`, `how much X`. Digit ↔ word
    equivalence (claim says "six", span says "6", or vice versa)
    with ordinal collapse (`sixth → 6`). Year-shaped digits
    filter out (those belong to the existing date anchor class).
    ALL-match semantics: every count token in the claim must
    appear in some cited span as digit or word.

(3) Why-cause shape — `why X`. Cause-anchor pool widens to
    ≥5-char lowercase common nouns (post a generic stopword set
    that filters quantifier-adjective fillers like "various",
    "factors", "situation") PLUS proper-noun anchors from the
    existing extractor. Gated on why-shape only: lowercase
    common-noun extraction has higher false-positive risk
    elsewhere.

Per-class policy gate (proposed `claim_lattice_warrant_classes`
dict) deferred per the five-step algorithm step 2: single
`warrant_check_enabled: bool` is the minimum viable gate; per-
class flags earn their slot when bench evidence shows over-firing
on a specific class.

17 new warrant tests (detector + extractor + integration).
Marker test in test_directives.py flipped from "absent" to
"present" assertion: test_d6_warrant_generalization_landed.

Full suite: 709 passed (was 692, +17).

Directive D6 status flipped to ✓ in seven-point-program.md.
Ticket #000003 closed.
