Upstream replacement: subconscious-systems#22

This PR was created in the fork in error. The fix and its issue are now submitted to upstream.

MAX_TRACE_BYTES limits ciphertext, but uploadVersion compares the cap against plaintext. Plaintexts in the last 16 bytes of the allowed range pass local validation and then fail server registration after expensive encryption.

Account for the 16-byte GCM tag before encryption or any network activity. A regression test checks the boundary and proves an oversized trace makes no request.

Validation: frozen-lockfile dependencies, typecheck, full tests, npm bundle build, and bundled CLI version/help smoke tests. The Ubuntu/Windows Node 20/22 branch CI must pass before this PR is created.

This PR is based on the CI foundation branch so its diff contains only this bug fix; merge the CI foundation PR first.

Closes #12.

All branch CI checks passed on 73b0ffa: https://github.com/dipeshbabu/vibi-cli/actions/runs/37263168612
