* Cap editing and text-layer caches that grew without bound The cos editing cache kept every touched object until save, so editing a large document pinned its whole object graph. Bound it like the scan reader: 1024 objects / 32 MB of owned bytes, 256 object streams / 32 MB, evicting to the newcomer. Returned objects outlive eviction, and clones share the caches, so this only costs re-parsing. The viewer text cache had the same shape: every visited page's text stayed for the session. Retain visible, selected and matched pages plus a 24-page prefetch window each frame; evicted pages re-extract on revisit. Skipped while a search is active, where demand still wants every page. Failures are never evicted: they cost nothing to remember. cli info on a 1024-page/147 KB file (debug build, same host/command): before 66.7 MB RSS, after 54.0 MB RSS (3 runs, tight). Tests: editor count bound, byte bound, snapshot-clone reads (cos); evict-far/keep-visible+matched+selection, search-active keep-all (canvas). All mutation-checked: each bound goes red when disabled.

Build one name index up front, O(F). entry().or_insert() keeps the old first-match semantics for repeated field names. New test with two same-named widgets pins first-wins and goes red under insert. 141 engine tests green, clippy warnings and perf lints clean.
