Spill oversized tool results without a name allowlist - #872

Fleet verbs are AgentTools and never entered the posix truncation plugin, so an allowlist of posix names could not cover wait_agents or search_agents. Leisure now applies to every non-error result over the gate, and the same helper wraps AgentTools at mount.
Nested tools wrap before the child session store exists. Live getters bind the writer after createSessionStores so oversized fleet and web results spill to a fetchable tool-output URI instead of a no-store notice.

Summary
Leisure materializes every non-error tool result over the size budget, not a named allowlist of shell and file tools. Fleet AgentTools are wrapped at primary and nested mount; nested overflow late-binds a blob writer so the spill URI is fetchable.
Fleet JSON (
wait_agents,list_agents,search_agents, lifecycle tools) used to skip truncation, so a parent that waited on a worker report got one giant JSON line and no URI. Nested workers wrapped tools before the session blob store existed, which produced a no-store notice.TRUNCATABLE_TOOLSis gone. Gate isisErrorplus size. Shell/file leisure algorithm is unchanged.tool-output:///{callId}:full. The blob recovers pretty JSON (minified fleet) or original text.getBlobWriter/getContextDir, assign the writer aftercreateSessionStores, then oversized nestedwait_agentsspills instead ofNOT retrievable.Verification
