content: in-document prose search via asText (763/763)

content/search-text + search-text-ids find every block whose (asText b)
contains a term — spanning all text-bearing fields by reusing the canonical
asText projection, so it can't drift from stats/find-replace. Section
wrappers excluded. +7 query tests.

 ## Progress log
 
+- 2026-06-07 — Feature: in-document prose search. `content/search-text` (and
+  `content/search-text-ids`) return every content block, tree-wide, whose
+  `(asText b)` contains a term — so search spans text/heading/code/quote/callout
+  text, image alt, list items and table cells **by construction**: it reuses the
+  one canonical "prose of a block" projection (asText) rather than re-listing
+  fields, so it can't drift from stats/find-replace. Section containers are
+  excluded (a term living only in a section's children returns the child, not the
+  wrapper). +7 query tests (cross-field match, count, single-field, no-match,
+  section exclusion, object return). 763/763.
+
 - 2026-06-07 — Consistency: `find-replace` now rewrites **every** text-bearing
   field, not just `text`. New `fr-rewrite` dispatches per block type — `alt` of
   image blocks, each item of list blocks, and every header/cell of table blocks
