fix(takes): keyword search matches words in long claims via word_similarity (#3267)

Both engines' searchTakes used whole-string trigram similarity
(claim % query), which structurally cannot pass the 0.3 threshold for a
short keyword against a 100-200 char claim — keyword search returned
zero results on real brains. Switch the predicate to word similarity
(query <% claim) and rank by word_similarity(query, claim), in both
postgres-engine and pglite-engine per the engine-parity invariant.
Holder allow-list and source-scope filters unchanged.

Regression test: single-word query must match a long claim containing
it (fails under the old predicate).

Fixes #3267

+
+- **Six fields inherit, child-wins:** `page_types`, `link_types`,
+  `frontmatter_links`, `enrichable_types`, `filing_rules`, and `takes_kinds`.
+  A child value with the same key (type name, link name, etc.) overrides the
+  parent's; keys the child doesn't declare come through from the parent.
+- **`page_types` ordering:** overrides of a base type keep the base's declared
+  position (base's `inferType` prefix priority is authoritative); a genuinely
+  new type — from the child, a `borrow_from`, or a middle pack in the chain —
+  is prepended nearest-first, so a more-derived type's `path_prefix` wins
+  regardless of how deep the chain is.
+- **`takes_kinds` is UNION, not replace** — it carries a Zod default, so an
+  omitted field is indistinguishable from an explicit one. A child can ADD
+  kinds but **cannot narrow** `takes_kinds` below base ∪ parent. If you need a
+  smaller set, don't `extends` a pack that declares the larger one.
+- **`phases` and `calibration_domains` are NOT inherited** (child-only). They
+  gate real cycle execution, so each pack must declare its own participation
+  explicitly — inheriting them would silently make a child run phases it never
+  requested. This is why `gbrain-everything` re-declares all its phases and
+  calibration domains by hand. See `lens-packs.md` for the worked example.
+- **`borrow_from` is selective + non-transitive + fail-closed:** it pulls only
+  the named `types`/`link_types` from the target's OWN declarations (omitting a
+  category borrows none of it); a missing target throws `UnknownPackError`.
