Update compat bounds, clean up docs, and modernize CI (#435)

- Tighten compat: HTTP "1", CodecZlib "0.7"
- Set minimum julia compat to "1.6"
- Simplify stdlib compat entries (drop 0.7 ranges)
- Use 'min' instead of hardcoded Julia 1.6 in CI test matrix
- Drop stale HTTP 0.9 compat from docs/Project.toml
- Remove checked-in docs/registry.md (auto-generated with broken URLs)
