Docs: multi-install-safe table out of date — missing `cline` and `zcode`

[mnriem]

Summary

The "multi-install safe integrations" table in docs/reference/integrations.md (lines ~185-201) lists 17 integrations, but 19 integrations are marked with multi_install_safe = True in code. Two are missing from the table.

Missing entries

Key	Isolation
cline	.clinerules/workflows, .clinerules/specify-rules.md
zcode	.zcode/skills, ZCODE.md

Both appear in the main agent table but not the multi-install-safe table, so users can't tell they are safe to co-install.

Evidence

• src/specify_cli/integrations/cline/__init__.py → multi_install_safe = True
• src/specify_cli/integrations/zcode/__init__.py → multi_install_safe = True
• Full code list (19): auggie, claude, cline, codebuddy, codex, cursor_agent, firebender, gemini, iflow, junie, kilocode, qodercli, qwen, roo, shai, tabnine, trae, windsurf, zcode

Suggested fix

Add cline and zcode rows to the multi-install-safe table in docs/reference/integrations.md. Consider a test or check to keep this table in sync with the registry.
