Merge PR #63: feat(soul) MCP connectors proxy + safety module + seeding ratio guard

Main already contained the connector proxy, safety module, seeding ratio
guard, and neuron-api node CRUD that Tim added — these were incorporated
via earlier parallel sessions. Taking main for all conflicted files
(superset implementations).

Unique contributions carried forward:
- flag_true() in routes.el: tolerates agentic:1 (integer) from the
  el-src UI in addition to agentic:true (bool) from the Kotlin UI.
- memory.elh: auto-merged timestamp bump.

The is_pending / skip-auto-persist logic was already in main's routes.el.
