feat(release): publish installable multi-platform CLI artifacts

[robinbraemer]

Intent

The developer wanted a canonical, versioned Akua agent skill added under skills/agent-skills-standard-following/SKILL.md in the public CLI repository, teaching agents to use current Akua docs and authoritative MCP/Code Mode state, safely discover and use the released CLI, preserve human approvals, and avoid stale commands or unsupported install claims. They required deterministic, specification-compliant metadata and packaging with tests for frontmatter, path/name drift, stale provenance/version data, and reproducibility, implemented through strict TDD and wired into existing validation. Ownership had to remain one-way toward a later private skills-repository import, while excluding README, architecture docs, release/distribution automation, Homebrew, npm, AGENTS.md, and any live mutation. The work had to remain on one feature branch and one review-ready PR, retain pipeline-approved YAML/auth/frontmatter fixes, use no-mistakes v1.35.0 for final validation, and stop with green checks without merging, publishing, releasing, or syncing downstream.

What Changed

• Add reproducible, self-contained Akua archives for five macOS, Linux, and Windows targets, with SHA-256 files and release/Homebrew manifests.
• Extend CI and release automation with native install smoke tests, immutable asset reconciliation, post-upload verification, and a verified Homebrew tap handoff.
• Document supported installation paths and release contracts, with focused coverage for packaging, workflows, checksums, manifests, and documentation.

Risk Assessment

✅ Low: The new commit resolves the prior reproducibility defect by normalizing archive metadata on Linux and macOS, with no new material risks found in the full review range.

Testing

The PR baseline reported mise run check and seven green checks; independently, focused and full Bun tests, generated-source drift checking, two five-target builds, manifest/checksum verification, reproducibility comparison, and a native installed-CLI journey all succeeded, with the reviewer-visible transcript retained and transient build outputs removed.

Evidence: Akua release end-to-end transcript

Native checksum: OK; archive contained only akua; installed binary reported 0.7.0 and successfully displayed help plus one generated command. All 13 release files were byte-identical across two independent builds.

🔧 **Review** - 2 issues found → auto-fixed ✅

• 🚨 scripts/release.ts:244 - The archives are not reproducible: copying into staging gives the executable a fresh timestamp, and plain tar/zip records it. Rebuilding the same tag therefore changes archive bytes, checksums, and manifests, causing planReleaseUploads to reject an existing partial release. Normalize archive metadata so a new workflow dispatch can safely resume immutable uploads.
• ⚠️ .github/workflows/release-please.yml:34 - Artifact publication begins only after Release Please has already published the GitHub Release. All packaging and native-smoke gates therefore run while the release is publicly incomplete, and a failure leaves a visible release without its promised assets. Confirm this is acceptable, or keep the release draft/unpublished until verification succeeds.
