`didOpen` for the wiki's index page fires almost immediately after
`initialized`, but the background `index_workspace` task hasn't yet
parsed the other pages. Link-health diagnostics computed at that
point look up every cross-page link target in a near-empty index and
flag them all as missing-page — and the diagnostics are never
recomputed once the scan catches up, so the editor shows stale red
squiggles on every link until the buffer is edited.
After each wiki's initial scan finishes, walk every open document
that lives in that wiki, recompute its diagnostics against the now-
populated index, and re-publish. Snapshots both the URI list and
each doc's `(ast, text, version)` so we don't hold DashMap iterators
across awaits.
