Boardstate 1.5.3

Fixed

• boardstate_workspace_replace no longer refuses a document for the two fields the server overwrites anyway.
  The server sets workspaceVersion (current + 1) and every tab's createdBy (the existing tab's owner, else the
  calling agent), but it validated the agent's raw values first. Agents that omitted or guessed them ("agent") got
  workspaceVersion must be an integer… or tabs[n].createdBy createdBy is invalid and retried until Hermes raised its
  tool-loop warning. The native handler now fills those two fields before forwarding; everything else is validated
  exactly as before, and the stored values are still the server's.

• Live Hermes data widgets showed their empty state ("No sessions yet.", $0.00) because nothing bound them: the
  renderer leaves binding the data-source builtins to the host, and neither the board templates nor agents did. The
  Agent HQ, Usage & Cost and Sessions Monitor templates now bind builtin:sessions, builtin:usage,
  builtin:instances and builtin:cron to their live RPC, and the native boardstate_widget_add /
  boardstate_workspace_replace handlers bind one an agent left unbound. An explicit bindings value is kept.

• Hermes 0.23 data shapes: the sessions widget reads is_active and last_active (it showed no live dot and no time),
  and cron.list reads /api/cron/jobs, falling back to /api/cron on older hosts. Session and job times are sent as
  epoch milliseconds, which is what the renderer displays.

Changed

• The native boardstate_workspace_replace description says those two fields may be omitted, and points small
  edits at boardstate_widget_add / boardstate_widget_update, which show on the board as each one lands. The
  native boardstate_widget_add description says live Hermes data widgets bind themselves, and the native
  boardstate_data_read description says live (rpc) bindings are resolved by the board, not by that tool (agents
  were calling it to verify a new live panel and getting an error).
• Screenshots of an agent-built launch board: docs/screenshots/launch-board.png and docs/screenshots/launch-tasks.png.

Known limits on Hermes 0.23

• builtin:instances stays empty: /api/status now reports active_agents as a count. The Usage & Cost template's
  "today" stat cards show "—": usage.status returns period totals, not today's. Both are tracked for a later release.
