Adds a gated admin endpoint that mints a fresh workspace bearer token on
demand, eliminating the register-race currently used by
test_comprehensive_e2e.sh (PR #5 follow-up).
- New handler admin_test_token.go: returns 404 unless MOLECULE_ENV != production
or MOLECULE_ENABLE_TEST_TOKENS=1. Hides route existence in prod (404 not 403).
- Mints via wsauth.IssueToken; logs at INFO without the token itself.
- Verifies workspace exists before minting (missing -> 404, never 500).
- Tests cover prod-hidden, enable-flag-overrides-prod, missing workspace,
and happy-path + token-validates round trip.
- tests/e2e/_lib.sh gains e2e_mint_test_token helper for downstream adoption.
- CLAUDE.md updated with route + env vars.
