Move updateEntry() calls after handleUpdateFrontmatter/handleDeleteProperty
in handleCustomizeType, handleRenameSection, and handleToggleTypeVisibility
so React state only updates after the disk write succeeds. This prevents
state-disk divergence when writes fail.
Expand ARCHITECTURE.md "Three representations, one authority" section with
ownership rules, invariants table, and recovery mechanisms. Add
reload_vault_entry to the commands table (62 total).
Add Playwright smoke test for Reload Vault in Cmd+K palette.
