Restore DOPEY public landing presentation

[Chris-ObtuseAI]

Summary

• restore the tighter product-style landing README from the private archive as the public repository front door
• preserve the public clean-slate boundary and replace private operational counts with public validation truth
• add the approved EVIDENCE BEFORE PROMOTION hero artwork
• retain the operating-loop and capability-topology diagrams plus the latest squeeze, bubble, IPO, options, autonomy, and governance capabilities

Validation

• python -m operator_tools.verify_public_source_boundary -> 2,679 tracked files verified
• README link/asset check -> 11 local links resolved, 2 Mermaid diagrams present
• dependency integrity -> passed
• staged diff check -> passed
• responsive hero artwork -> 1731 x 909 PNG

Local environment note

• local Python is 3.13.13 while CI is pinned to 3.11
• a focused 3.13 run produced 8 passes and one existing import-hook isolation failure; required protected-branch Python 3.11 shards are the authoritative result
