## Background
Environment variables are currently used for a few practical boundaries: XDG-style path discovery, runtime/socket directories, development overrides, and legacy/provider secret inputs. The user's preference is that this project should avoid environment variables where possible and make any remaining environment-variable surface explicit.
A short investigation found that path resolution is mostly centralized in `manifest::paths`, while auth/web secret envs and test-only env mutation are more scattered. Normal runtime intentionally does not implicitly load `.env` files.
## Requirements
- Add current documentation for environment-variable policy and supported variables.
- State the design preference clearly: avoid new environment variables when manifest/profile/config/typed secret references are better.
- Document the currently supported categories:
- core path/resource discovery;
- runtime/socket/registry discovery;
- Pod runtime command development override;
- provider/WebSearch credential references;
- external compatibility variables such as Codex home;
- test/build/example-only environment variables.
- Clarify that normal runtime must not implicitly load `.env` files.
- Identify cleanup direction without implementing unrelated refactors in this ticket.
## Acceptance criteria
- A user/developer-facing docs page explains environment-variable policy and current variables.
- Existing Nix/config docs link to the new policy page where relevant.
- Documentation does not expose secret values or read ignored secret-like files.
- `./tickets.sh doctor` and `git diff --check` pass.
