Promote dev to main

[emmepra]

Summary

• promote the cleaned dev state to main
• carry the simplified public README and institution-first citation metadata onto the stable public branch

Scope

• in scope:
  • branch promotion from dev to main
• out of scope:
  • additional code changes
  • release changes

Validation

• relevant tests/checks were run
• Docker/runtime validation was run when the change touched backend, orchestration, templates, or integration paths
• docs/rules were updated when behavior, contracts, or workflow changed

Commands run:

git fetch origin

Risks

• user-visible regressions:
  • main will move forward to match dev
• operational/runtime risks:
  • low; this is a branch promotion of already integrated work
• follow-up work:
  • none

Evidence

• logs: branch sync and merged PR history on dev
• screenshots: none
• related issues: none
