 The manifest owns the user-facing AgentProvider shape. This module is
 the launch-time table that turns a provider template into an executable
 command, default image, and prompt/auth behavior.

+Per PRD 0050 the per-provider implementations live under
+`bot_bottle/contrib/<template>/agent_provider.py`. This module exposes:
+
+  - `AgentProvider` (ABC) — the contract each plugin implements.
+  - `get_provider(template)` — lazy-imported registry; the analogue
+    of `bot_bottle/deploy_key_provisioner.get_provisioner`.
+  - `AgentProvisionPlan` (+ helper dataclasses) — declarative shape
+    each provider produces and the backends consume unchanged.
+  - `agent_provision_plan` / `runtime_for` — thin wrappers around the
+    registry kept so existing callers keep working without per-call
