The previous fix regenerated the MCP config per call but still pulled the tool
set from pi.getAllTools(), which depends on the runtime binding being scoped to
the right AgentSession. Engine-spawned triage/executor sessions register custom
tools (fn_review_spec, fn_review_step) and pi-ai already passes those to the
provider via Context.tools — that's the authoritative per-session list and
bypasses any binding ambiguity. Falls back to pi.getAllTools() when the caller
doesn't populate Context.tools.
Also logs the tool names on refresh so missing tools are diagnosable from stderr.
