docs: fix stale milla-jovovich org refs and branch target in contributor docs (#679)

The repo moved to the MemPalace org but several docs still point at the
old milla-jovovich URLs.  Also, CONTRIBUTING.md tells people to PR
against main while the actual workflow (per ROADMAP.md) targets develop.

Files touched:
- CONTRIBUTING.md: clone URL, issues URL, PR target branch
- examples/gemini_cli_setup.md: clone URL
- integrations/openclaw/SKILL.md: homepage and license URLs
