Addresses Greptile review on PR #407:
- P1: setup-keychain.sh ALL_KEYS was missing GOOGLE_GENAI_API_KEY and
XIAOHONGSHU_API_BASE relative to _load_keychain's inline list, so users
manually storing those keys would not see them in --list and the
interactive prompt would never offer to set them.
Hoist the canonical key list into lib/env.py::KEYCHAIN_KEYS, have
get_config() pass it through, and add a parity test that parses
ALL_KEYS out of setup-keychain.sh and asserts equality. Drift is now
caught at CI time instead of after a user reports a missing key.
- P2: os.environ.get("USER", "") silently returned "" under sudo, in
Docker without --env USER, or in CI runners that strip USER. The
resulting `security find-generic-password -a ""` call would never
match items stored by setup-keychain.sh, so all lookups silently
returned nothing. Fall back to pwd.getpwuid(os.getuid()).pw_name when
USER is absent.
The P2 process-listing comment ("secret visible briefly via ps because
security has no stdin path for -w") has no clean fix — the README
already documents the manual `security add-generic-password` invocation
as an alternative for users with strict secret hygiene.
