Merge master into PR #156 (remote tmux durability)

Resolutions:
- session.ts: keep the extracted _buildRespawnPaneOptions() helper (COD-108)
  and add master's docker/owner fields to it
- tmux-manager.ts: docker branch first, then remote via buildRemoteSessionCommand
  (now an options object threading claudeMode/allowedTools into
  buildRemoteLaunchCommand, preserving the 6.3 multi-user permission downgrade)
- case-routes.ts: keep master's adminOnly helper; gate the new COD-105 discovery
  endpoint admin-only in multi-user mode (hosts are machine-level infra)
- settings-ui.js: union of remoteAutoReconnect + master's header-button defaults
- session-routes.ts: union of imports; session gets remote + owner
