Two refs in README.md:
- Sister-repo cross-link `hermes-channel-molecule` (line 5)
- Anonymous `git clone` install command in Development section (line 73)
Both rewritten to the canonical Gitea path
(https://git.moleculesai.app/molecule-ai/...). Anonymous-clone semantics
preserved — no auth-shape change, repos are public on Gitea.
Other github.com refs in README (openai/codex links) are upstream
references and remain unchanged.
Refs: molecule-ai/internal#37, molecule-ai/internal#38
