v0.18.0 — Unified capability nomenclature

This release unifies the naming of every Dapr building block around the short name Dapr uses in its HTTP path, keeping Scala conventions (UpperCamel, *Capability suffixes). One concept, one stem — no more ServiceInvocation vs Invoker vs Invocation for the same thing.

⚠️ Breaking change. Public capability traits, op-types, companion accessors, the DaprApp route field, and several model types are renamed. Mechanical find-and-replace upgrades most code; see the mapping below.

Highlights

• ServiceInvocationCapability / Invoker* / Invocation* → Invoke* (matches /v1.0/invoke)
• PubSubCapability → PublishCapability (the client capability is publish-only; PubSubName kept — it is Dapr's literal pubsubname)
• DistributedLockCapability → LockCapability (matches /v1.0-alpha1/lock)
• Config* → Configuration* (matches /v1.0/configuration)
• Conversation value types singularised to match their cardinality

Refactors

Service invocation → Invoke

• ServiceInvocationCapability → InvokeCapability
• InvocationRoute → InvokeRoute, InvocationRequest → InvokeRequest, InvocationMethodName → InvokeMethodName
• Derivations ServiceInvocation/InvocationRoutes/ServiceInvocationDerivationRuntime → Invoke/InvokeRoutes/InvokeDerivationRuntime
• Accessor DaprCapability.invoker → DaprCapability.invoke; DaprApp.invocations field → DaprApp.invokeRoutes

Pub/Sub → Publish

• PubSubCapability → PublishCapability; accessor DaprCapability.pubsub(...) → DaprCapability.publish(...)
• PubSubName unchanged (Dapr's component identifier)

Lock

• DistributedLockCapability → LockCapability

Configuration

• ConfigKey/ConfigStoreName/ConfigValue/ConfigVersion/ConfigItem/ConfigUpdate → Configuration*
• Accessor DaprCapability.config(...) → DaprCapability.configuration(...)

Conversation

• ConversationTools → ConversationTool, ConversationToolCalls → ConversationToolCall, ConversationResultChoices → ConversationResultChoice

Bindings

• Accessor DaprCapability.binding(...) → DaprCapability.bindings(...)

Docs

• DESIGN.md, SPEC.allium, derivation.md, validation.md, and AGENTS.md updated to the new nomenclature.

No behavioural changes — renames only. Verified with the full unit (33) and integration (90) suites green.
