F4 SLICE-5: host E2E (propose/accept/reject/persist/stale/coexist) + seam fix: event-level net-effect matching survives host word-diff splitting (INV-9) (#12)

The accept E2E exposed a latent F3 limitation: VS Code word-diffs one
applied WorkspaceEdit into several minimal hunks when old/new share
interior tokens, so the registry's per-hunk exact match missed and seam
edits fell through as fragmented human spans. PendingEditRegistry.match
is replaced by matchEvent (all hunks inside the registered full range +
equal net delta — one applyEdit is one change event). Plan AMENDMENT 1.
