github.com/caddyserver/zerossl v0.1.5: Client.DownloadCertificate, Client.RevokeCertificate, Client.CancelCertificate

# caddyserver/zerossl API Client Usage and Contract Verification

## Search Results
A search via `search_known_solution` for the package `github.com/caddyserver/zerossl@v0.1.5` returned `NO_SAFE_MATCH`.

## Implementation and Behavior Proved
1. **Certificate Bundle Download**: `zerossl.Client.DownloadCertificate` queries `/certificates/{id}/download/return` with `include_cross_signed` and parses returned JSON bundle (`certificate.crt`, `ca_bundle.crt`).
2. **Certificate Revocation**: `zerossl.Client.RevokeCertificate` sends a POST request to `/certificates/{id}/revoke` with the revocation reason (e.g. `zerossl.KeyCompromise`) in query parameters and verifies operation success.
3. **Certificate Cancellation**: `zerossl.Client.CancelCertificate` sends a POST request to `/certificates/{id}/cancel` to cancel draft/pending certificates.
4. **Validation Status Querying**: `zerossl.Client.VerificationStatus` queries `/certificates/{id}/status` to inspect verification completion status and per-domain validation method details.

Clean-room public code sample — generation instructions

Write a brand-new, minimal, self-contained code sample in this clean-room directory.
Do not copy, paraphrase, or reference any existing project source. Work only from this spec.

A csx.json manifest scaffold already exists. Do not recreate it from memory. Preserve its case.goal, packages and symbols; fill its empty case.contract with exact assertions and correct its environment, commands and verifierAdapter for the files you generate.

Goal: verify pkg:golang/github.com/caddyserver/zerossl@v0.1.5
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:golang/github.com/caddyserver/zerossl@v0.1.5
Constraints:
  - executionContext: node
Required runtime conditions:
  - ecosystem: npm
  - language: javascript
  - moduleSystem: cjs
  - packageManager: npm@10.9.8
  - runtime: node@22.23.2

Rules:
  - One focused purpose; the smallest project that proves the goal.
  - Include a contract test (test/contract.*) that runs OFFLINE and exits 0 exactly when the goal behavior works.
  - Pin every dependency with a lockfile so resolution is reproducible.
  - No secrets, credentials, or tokens. No real URLs (only example.com or localhost). No absolute paths.
  - No personal names, emails, company names, or project identifiers of any kind.
  - No binaries and no generated output (node_modules, dist, target, venv, .git, .env).
  - Keep it under 200 files and 256KB packed.
