node-tools hands each bundle its own environment (hq ADR 0192)

Browse Source 
The mesh composes every served module's words into MESH_TOOL_ENV; the runtime takes it at start
and removes it from its own environment, then gives each registration's contributor and each
launched child the runtime's words plus its own module's, never another's. Against an SDK
without collectToolsEach it says so and serves with the runtime's words only. The test serves
two imported bundles and one launched, each answering with its own words and none of the others'.
