fix(agent): resume always-on SWM after restart

[branarakic]

User impact

After an Edge node restarts, a graph that the user explicitly persisted as always-on now resumes both finalized VM synchronization and live/shared-memory synchronization. Broad Edge sync remains disabled: on-demand, runtime-only, unselected, AGENTS, and ONTOLOGY graphs are not pulled by this periodic path.

This closes the live canary failure where VM resumed for the selected graph after restart but SWM was skipped because the global syncSharedMemoryOnConnect=false default was applied to the graph-scoped periodic reconciler.

Safety boundary

• The override applies only to the module-private periodic Edge invocation whose scopes are derived from startup-rehydrated, persisted always-on subscriptions.
• The ordinary peer-connect path still obeys the global syncOnConnectEnabled and syncSharedMemoryOnConnect switches.
• Core behavior and system-graph inclusion are unchanged.

Validation

• pnpm --filter @origintrail-official/dkg-agent build
• Focused sync-coverage-evidence-runtime.test.ts: 22/22 passed
• Full Agent unit lane: 165 files, 2,243 passed, 5 skipped, 0 failed
• git diff --check
