🔄 rebrand: moltbot → openclaw, clawdinators
Rename org references from moltbot to openclaw across all config, docs,
CI workflows, flake inputs, secret names, and repo seeds.
Mapping:
- org: moltbot → openclaw
- repos: moltinators → clawdinators, nix-moltbot → nix-openclaw, molthub → clawhub
- secrets: moltinator-* → clawdinator-*
- flake input: nix-moltbot → nix-openclaw
- GH repos renamed: openclaw/nix-openclaw, openclaw/clawdinators
Upstream package/binary names (moltbot, moltbot-gateway, moltbot.json)
kept as-is — those come from nix-openclaw and haven't been renamed yet.
Tests: not run (rename-only change; CI will validate flake eval)
