Module runtime 

Runtime lifecycle, concurrency, and resource governance (JOE-1573).

Modules:

• op_context — per-operation cancel/deadline/progress
• governor — process/engine admission permits and overload policy
• singleflight — per-key load coalescing
• registry — weighted model residency and eviction
• lifecycle — Running → ShuttingDown → Stopped (for FFI / process)

Profiles

GovernorConfig::default is a conservative desktop profile. Use GovernorConfig::mobile or GovernorConfig::server for known deployments. Process-global defaults live on ResourceGovernor::process_global.
