feat!: add image source files and system messages Separate editable image sources from generated commit revisions and loaded actor implementations. Add the source filesystem and context actions in VS Code, path-based REPL commands, sender-aware actor contexts, and privileged lifecycle controls. BREAKING CHANGE: protocol v4 replaces published behavior commands with image source paths and commit operations. Actor handlers now use handle(ctx, state, sender, message) and return only state; outgoing messages use ctx.send or ctx.send_from.

feat!: remove actors on stop and kill and default counter state Remove actors after successful graceful shutdown or immediately on kill, including state, mailbox, logs, and source-path metadata. Keep failed actors available for inspection and repair. Preserve restart as an independent identity-retaining operation and mark removed VS Code snapshots read-only. Default the self-incrementing counter's missing state to zero on its first message and isolate finite control-test fixtures from the demo. BREAKING CHANGE: stop and kill permanently remove actors instead of retaining stopped instances. Removed references cannot be inspected, sent to, or restarted. Use restart directly to retain actor identity and state.

feat: add minimal single-worker actor runtime Implement typed, budgeted Rune invocation slices and a minimal in-memory actor runtime with bounded mailboxes, state transitions, effects, and lifecycle operations. Add feasibility and runtime documentation with tests for async resumption, cancellation, and scheduler fairness.

feat!: add structured actor state and messages Introduce owned portable values with distinct actor references, bounded Rune conversion, JSON REPL literals, and nested reference completion. Preserve isolation and atomic transitions across state, messages, effects, migration, inspection, and TCP clients. BREAKING CHANGE: protocol v3 replaces integer state and kind/value/target_ref messages with tagged values. Rune handlers now take (state, message) and return (new_state, [(actor_reference, message)]). The REPL send command accepts one JSON message.
