docs: full sync ahead of compaction + config-management overhaul

readme: manager mcp surface picks up update; operator-surface
recap mentions /model + last-turn + model chip + the three
collapsibles (inbox / journald / agent.nix).

web-ui.md: details-restore-key story under shape; port-conflict
banner mention on containers; agent.nix viewer alongside journald;
notifications use per-event tags + console.debug log on
block/show; deny endpoint takes note=<reason>; data-prompt /
data-prompt-field generalisation noted.

conventions.md: data-prompt and snapshot/restoreOpenDetails added
to the async-forms section.

persistence.md: operator_questions row picks up deadline_at (ttl)
column with a migration note.

todo.md: new 'Bugs' section captures the manager-question
not-rendering issue with three suspect paths to chase.

claude.md scratchpad rewritten as a clean handoff for the
compaction + the upcoming config-git overhaul. flags the
two-repo (proposed/ + applied/) split as the thing to
reconsider.
