v0.0.21

• Dev-context injection is now default-on (qfg-bw7g.5). enable_quonfig_user_context now defaults to nil (unset). When left unset it defaults to on, gated solely by the presence of ~/.quonfig/tokens.json; the loader no-ops without that file, so this stays inert in production. New dev_context_enabled? precedence: explicit enable_quonfig_user_context option ?? QUONFIG_DEV_CONTEXT env (true/false) ?? true. Pass enable_quonfig_user_context: false or set QUONFIG_DEV_CONTEXT=false to opt out.
