Files older than the feature components/text-overrides mark a copy text
with :text-content-attribute (any style) or :text-content-structure
(letters and styles). Migration 0034 compares each such copy with its
near main and gives it the groups its old flags allowed where it
differs; an old flag where nothing differs sets nothing. A copy whose
near main cannot be reached keeps every group its flags allowed, so it
loses no override. The migration adds the feature, so a client on the
old code cannot write the old groups into a migrated file.

Binfile import leaves the copies whose near main is in a library not
linked yet, as it does with swap slots, and converts them once the
libraries are linked: the deferred pass of the import now runs both
conversions (convert-deferred!, *defer-unreachable*).

Validation reports the old groups (:legacy-text-touched), and its
repair recomputes them against the near main; a text override group
without :content-group is still :invalid-text-touched. A shape with no
letters in it and its main no longer counts as differing in its styles.
