v0.8.0

Workers

• Worker runtime integration — workers now execute through a dedicated WorkerHandler surface instead of only piggybacking on generic delivery handlers, which gives the runtime a typed capability boundary for execution plus result handling.
• worker:// feedback path — successful worker results are now materialized into runtime-owned worker://name sources on the next tick, so arbiters can reason about worker outputs without collapsing into an imperative in-tick sublanguage.
• Typed worker output enforcement — worker executions now validate returned fact/outcome shapes against the declared worker contract, and unknown worker://... source references are rejected at compile time.

Tooling

• Explore and CLI visibility — arbiter explore summaries and compile/check surfaces now expose worker and arbiter declarations directly instead of hiding them behind the raw IR.
• Editor highlighting — VS Code and tree-sitter highlighting now recognize worker, arbiter, runtime handler keywords, and worker contract clauses.

Release

• Version bump to 0.8.0 — SDK, editor package, and release metadata now align on 0.8.0 for the fully integrated worker runtime release.
