ruview-harness-v0.3.0

## RuView community metaharness 0.3.0

This release turns the RuView harness into a secure, shared contributor control plane while keeping the published package runtime-dependency-free.

### Highlights

- Local Claude Code (claude -p) and Codex (codex exec) adapters with stdin prompts, safe/read-only defaults, trusted-root checks, bounded subprocesses, environment allowlisting, and secret redaction.
- A reviewed, source-cited shared repository brain plus an unreviewed proposal flow for community contributions.
- Exact-pinned MetaHarness, Darwin, and Flywheel development tooling with frozen anchors, holdouts, signed replay verification, and maintainer-controlled promotion.
- Default-deny MCP mutation policy, strict schemas, bounded request/queue handling, queued cancellation, and metadata-only audit events.
- Cross-platform provenance manifest, immutable CI action pins, zero npm audit vulnerabilities, and 53 passing tests.
