fix: report plugin version in hello JSON

[myagentdojo]

What changed

• Add pluginVersion to hello --json.
• Bind the Bun compatibility adapter to canonical plugin metadata.
• Require packaged distribution proof to preserve the version marker.

Why

The live marketplace auto-update acceptance needs a payload-owned signal that distinguishes the installed version. Marketplace metadata alone cannot prove that the harness selected and executed the refreshed payload.

Impact

Agents can read the executed plugin version directly from the offline JSON result. Existing fields and plain-text output remain unchanged.

Validation

• bun run prove:all
• 309 tests passed, 3 interactive/hosted cases skipped by contract
• QuickJS and Bun output equivalent
• Deterministic package proof passed
• Native Claude and Codex install proof passed
• Fallow: 0 introduced findings

Summary by CodeRabbit

• New Features

  • The hello --json command now reports the installed plugin version alongside its command result, success status, and run ID.
  • Runtime execution automatically uses the configured plugin version when generating responses.

• Bug Fixes

  • Improved packaged launcher validation to ensure reported plugin versions match the installed configuration.

• Tests

  • Added coverage confirming successful JSON responses include accurate plugin version information.

📝 Walkthrough

Walkthrough

The runtime now loads the configured plugin version and exposes it to command execution. The hello --json response includes this version. Tests and distribution validation verify the reported value.

Changes

Plugin version reporting

Layer / File(s)	Summary
Runtime version wiring runtime/src/bun-proof-adapter.ts	The adapter loads plugin.config.json, assigns its version to globalThis.PLUGIN_VERSION, and dynamically imports executeCommand.
Hello response and validation runtime/src/portable-command.ts, plugin/runtime/hello-world.js, runtime/src/portable-command.test.ts, scripts/prove-distribution.ts	The hello --json response includes pluginVersion. Tests and packaged-launcher validation check the configured version.
Estimated code review effort: 2 (Simple)	~10 minutes
