chore(release): prepare final runnable preview 0.1.0-preview.113

[TypeThe0ry]

What changed

• publish the final runnable Windows/Linux preview as 0.1.0-preview.113
• include the stale AGENTS.md receipt reconciliation fix and preserve user-restored bytes
• retain macOS detached-process identity hardening while keeping managed execution fail-closed
• refresh README, audit, project status, and changelog for the final candidate

Validation

• version consistency and prerelease negative gates pass locally
• changelog consistency passes locally
• PR fix: finalize cross-platform runtime tracking and release docs #220 merged after full CI, including Windows install lifecycle, managed worker kits, and Windows controller/worker live round-trip
• PR deps(actions): bump the github-actions group with 10 updates #216 action dependency update merged after full CI and Windows Setup acceptance
• stable v0.0.1 remains immutable

This is intentionally a public prerelease. macOS managed execution remains explicitly fail-closed until native host evidence is available; no stable tag is moved.
