补充手工测试（用户 2026-07-27）

grant create sess + Tab → 误补为 session_user，期望补全角色/关键字 session（GRANT CREATE SESSION）。

与既有 alter sess→session_user 同类，请统一评估 session / session_user 优先级。

已修复

SQL> alter sess
-- 按一次 Tab

回归版本：oGRAC Release 7.0.0-RC3 18ce0a2 build 2026-08-26 09:48:01
回归环境：oGRAC 双节点（20.20.20.104 / 20.20.20.106），db=ONLINE，节点 20.20.20.104 执行
结论：通过（alter sess / grant create sess 补全为 session，不再误补 session_user）

回归步骤（ogsql / as sysdba，Linux TTY）

SQL> alter sess<Tab>
SQL> grant create sess<Tab>

实际输出
分别变为 alter session、grant create session。pty 自动化断言通过。
