Foundation slice for Mantis #841 php/Mod/Agent RFC implementation:
* CompleteTask now wraps in DB::transaction with idempotent credit awards
and safe current_task_id clearing
* Credits/{Award,GetBalance,GetCreditHistory} updated for agent_id +
fleet_task_id ledger support and richer balance totals
* GenerateCommand canonical agentic:generate wiring; legacy duplicate
no longer registered
* Boot wires brain:clean / brain:prune / brain:reindex
* EmbedMemory exits early when memory already indexed
* 3 follow-on fleet migrations reconcile fleet_nodes pointer column,
fleet_tasks/credit_entries fk/index hygiene, fleet+credit constraints
* 4 foundation tests under php/tests/Feature/Mod/Agent/
php -l clean on all modified files. pest unrunnable in sandbox (no vendor/).
Foundation slice only: remaining model/action parity, full MCP tool/
service sweep, fleet controller auth-context, and 41-tool/45-action
surface left for follow-up tickets.
