legal: adopt asset-specific licensing and IP notices

[BotshareAI]

Summary

• adopts the OpenAMRobot asset-specific licensing standard:
  • MIT for software and firmware
  • CC BY 4.0 for documentation and original media
  • CERN-OHL-P-2.0 for hardware source, CAD, schematics, manufacturing source, and CAD-derived geometry
• identifies OpenAMRobot (Botshare LTD) consistently while preserving third-party rights
• standardizes licensing and provenance contact to info@botshare.ai
• explains that prior valid licence grants remain effective
• adds or updates repository-specific metadata and notices where applicable

Safeguards

• no third-party material is relicensed
• trademarks and branding are excluded from the open-content grants
• mixed repositories use LICENSING.md plus more-specific file/directory notices
• DCO and CLA checks remain required by branch protection

Review focus

Verify repository classification, third-party notices, asset provenance, and any file-specific exceptions before merge.
