mind-body: tear out dollar metering; a shared tempo heartbeat; usage-only connector (WIP, tests follow)

Browse source 
Delete the classifier, initiative, burn, base-rate dial, shares, Envelope dollars,
persona turn max_cost, --max-budget-usd and the Self-run settle. Add tempo::tally
and tempo::pick, self-declared urgency from the reply as a Pulse, the usage line in
Persona input, and the wire-v4 connector (lease v2, usage_readout).
