chore(tcloud): release Sandbox evidence compatibility

[drewstone]

Change

Release @tangle-network/tcloud 0.8.0 with Sandbox >=0.58.4 <0.59.0.
The lockfile resolves the now-public Sandbox 0.58.4 artifact.
This provides the compatible transport dependency for the current research cohort.

Proof

• Normal install used the public Sandbox 0.58.4 artifact.
• All eight first-party range script checks passed.
• The owning build emitted runtime bundles and declarations.
• TCloud suite: 297 passed, 32 live cases skipped, 329 total.
• The real TCP transport proof passed direct chat, search, retry cancellation, and relayed cancellation.
• Each cancellation closed its request without retry; elapsed times were 136–166 ms.
• Concurrent per-response cost receipts remain distinct; missing cost remains absent.
• A priced response without token usage updates spend and prevents another request after the limit.
• Packed artifact inspection, clean installed consumer bundle, and the owning dependency-age consumer passed.
• Candidate SHA1: 6284f2620e94bcb377e5fe158f5c19db0cee26a2.
• Existing commit/push hooks passed; the actual target merges cleanly.
• Source: 6095eff on drew-gtr-pro.

The separate tcloud-agent package retains its earlier SDK dependency.
The compatibility claim applies to the standalone TCloud package and its consumer graph.

Independent cohort review APPROVED at exact source 6095eff. The review confirms d708870..HEAD changes only standalone version 0.8.0, Sandbox >=0.58.4 <0.59.0, and normal generated lock resolution. Standalone reachable dependencies exclude the separate old tcloud-agent SDK cohort. No source finding remains.

Exact-head sdk CI is SUCCESS, all normal local release checks and hooks passed, and main merges cleanly. The final Lab singleton claim belongs to its fresh installed consumer. The release source claim remains the standalone TCloud package.

Proceeding with the maintained merge/tag publisher under standing owner authorization.
