Replace the old "patches" format (path:lang composite keys, ordered
hunk lists, text-anchored matching) with Data.overrides:
path -> lang -> LangEdits, keyed throughout so a save's database diff
touches only the edited chunks. The old "patches" key is ignored on
decode, discarding legacy data without a migration.
- Whole-paragraph additions/deletions are structural: a drop flag on
the original chunk hash, and additions in their own dict anchored
from the neighboring chunks' before/after (first live referrer wins),
so they stay in place across retranslation and one-sided original
edits.
- Within-paragraph edits (up to a full paragraph rewrite or split) are
full-chunk replace patches applied by chunk hash alone: a
retranslation is overridden wholesale, so user edits survive AI
re-runs; editing the original changes the hash and orphans the patch.
The old search-matching staleness gate is gone.
- Saving a translation on a page without original chunks is rejected
(REST 400 / WS error); emptying the original afterwards renders the
translation empty, with the orphaned overrides inert.
